Apologies for the shouting but this is important.
When answering a question please:
- Read the question carefully
- Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
- If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
- If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.

For those new to message boards please try to follow a few simple rules when posting your question.- Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
- Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
- If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode "<" (and other HTML) characters when pasting" checkbox before pasting anything inside the PRE block, and make sure "Use HTML in this post" check box is checked.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question into an unrelated forum such as the lounge. It will be deleted. Likewise, do not post the same question in more than one forum.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.

Hello to everyone,
it might sound funny, but in a current project "suddenly" (i.e. I don't know what I exactly did) the references to "My.Settings" didn't work anymore. Instead, I had many errors saying that "Settings" isn't a property of "My".
What I did: I opened a completely new (winforms-) project and looked into the files having "My.Settings" (etc) in their text, and adapted my project files "app.config", "settings.settings" and "settings.designer" (manually inserting the properties) to the syntax and entries I saw in the new (sample) project.
First I thought it's ok: All the error messages disappeared. But when debugging, I can see that my settings references (e.g. "My.Settings.UserPath") only supply empty strings. This implies to me that the valid entries must be out of the valid scope (or something like that), i.e. I must have overlooked something... typos are checked.
Could one of you please advise me, where else I might look for errors or what else I could do?
Thank you very much in advance,
Mick

Go to PROJECT -> Properties on the VS menu. Or right click on the project in the Solution Explorer window and select Properties. You should then be able to navigate to the Settings section.

Thank you, Richard - but both methods work normal and I see the usual page with my user settings.
The problem occurs when "InitializeComponent" callsPrivate _userSourcePath As String = My.Settings.UserSourcePath <--------------
Public Property UserSourcePath() As String
Get... which is called by , returns an empty string instead of the actual settings entry.
I think I must have made an error when manually editing the mentioned files. For example, I don't know where I would place the Namespace reference in "app.config" or in the settings files.
Any other idea?

Sorry, no. But I would certainly not recommend manually editing these files, as it is too easy to make a mistake that does not show up until you try running the code. I can only suggest you recreate your project and settings via Visual Studio.
|
|
|
|
|
Thank you though, Richard.
Finally I found the problem: The file "settings.designer.vb" had it's first part of the code (where the properties are defined) wrapped into "Namespace My"/"End Namespace". Obviously that's not right and lead to wrong references / empty string.
Now it works again  !
Have a nice day,
Mick

In a vb.net 2010 application, I am trying to determine the best way to accomplish this goal.
Write now 1 letter is generated and sent to one guardian. However this application needs to be
changed so that the same exact letter can be send to different mailing addresses since each student may have more than one parent/guardian at different mailing addresses. So basically I want to generate more than one letter with the same wording. The only differences between the letters would be the mailingaddresses. I want the letters to be written to the same varchar(max) column in a sql server 2012 database. The letters will be in the same field since the data will be sent to a sql server reporting server where the letters will be generated one after each other.Right now the letters are written to the 'Dim _al As Letters = New Letters()' object. The only way I know to modify text data is to use a string or stringbuilder objects. I do not know yo modify data is other objects. Basically I want to use a string.replace logic to replace the addresses in the second letter. I also want to use
stringbuilder.append to place more than one letter following another to be placed in the osne varchar(max) field.
I know I can use the following code to convert a custom object to a string.
Dim _LetterStr As String = String.Empty
Dim _LetterStrbldr As StringBuilder = New StringBuilder
_LetterStr = _Letter.Letter.ToString()
However I do not know how to convert a string object back to a custom object.
Here is the original code of the application:
#Region "Protected Sub btnSubmitModifiedLetter_Click(ByVal sender As Object,
yVal e As System.EventArgs) Handles btnSubmitModifiedLetter.Click"
Protected Sub btnSubmitModifiedLetter_Click(ByVal sender As Object, ByVal e
As System.EventArgs) Handles btnSubmitModifiedLetter.Click
Dim _al As Letters = New Letters()
Dim _infinteCampusText As String
Dim _Letter As Letter = New Letter()
Dim _startDate As DateTime = Now()
Dim _term As Integer = 0
_Letter.SchoolYear = _schoolyear
_Letter.Term = _term
_Letter.Milestone = ddlMilestone.SelectedValue
_Letter.SchoolNumber = Right("000" & ddlSchools.SelectedValue,3)
_Letter.Printed = "Y"
_Letter.Letter = reLetterEditor.Content
_Letter.StudentLink = Right("0000000" & txtStuLink.Text, 7)
_Letter.Language = txtLanguage.Text
_infinteCampusText = _al.BuildText(_Letter)
_al.InsertData(_Letter, _infinteText)
btnProcessSelections.Visible = False
gvLetters.DataSourceID = String.Empty
gvLetters.DataBind()
gvLetters.Visible = False
Response.Redirect("letter.aspx?schoolyear=" +
_Letter.SchoolYear.ToString() + "&schoolnum=" +
_Letter.SchoolNumber.ToString() + "&term=" +
_Letter.Term.ToString() + "&milestonecode=" +
_Letter.Milestone.ToString() + "&startdate=" + _startDate.ToString() +
"&enddate=" + DateAdd(DateInterval.Day, 1, Today()).ToString() +
"&language=ALL&studentlink=ALL")
End Sub
#End Region
Thus can you show me the code to convert a string object to a custom object and/or show me code on how to accomplish my goal?
|
|
|
|
|
Why would you need to do such a conversion? All you need is a template that contains the main text of your letter, a _Letter object that contains the different properties (name, address etc), and a subroutine that formats the data into its printed form.
|
|
|
|
|
Would you show me an example of the code you are referring to? How should I convert a string object to a custom .net object?
|
|
|

Quote: How should I convert a string object to a custom .net object?
No idea, the question does not really make sense, since String is already a .NET object.

I'll attempt to answer your question, but if it were me, I think I would re-design this solution. Do you really need to store the letter in the database ? Maybe create a template letter, give it a unique document ID, then you could store multiple records with the student ID, template ID and sequence number.
To answer your question ...
Create a class and call it LetterDetail; at a minimum it would have a string to store the letter.
Create another class and call it MailedLetters; this would contain a List(Of LetterDetail)
The second class gives you the ability to have as many letters as you want grouped together.
Within the second class, you would need 2 methods, Save and Load. This would serialize the object to an XML string which you could then save in the database.
I'll give you some rough code for serialization ...
Public Shared Function Load(sFname As String) As MailedLetters
Dim xr As XmlReader
Dim settings As XmlWriterSettings = New XmlWriterSettings()
settings.Indent = True
settings.IndentChars = (ControlChars.Tab)
settings.OmitXmlDeclaration = True
Dim obj As New MailedLetters
Dim mySerializer As New XmlSerializer(obj.GetType)
xr = XmlReader.Create(sFname)
obj = mySerializer.Deserialize(xr)
xr.Close()
xr = Nothing
Return obj
End Function
Instead of serializing to a file, you want to serialize it to a string.
Sub Save(sFname As String)
Dim xw As XmlWriter
Dim mySerializer As New XmlSerializer(Me.GetType)
Dim settings As XmlWriterSettings = New XmlWriterSettings()
settings.Indent = True
settings.IndentChars = (ControlChars.Tab)
settings.OmitXmlDeclaration = False
xw = XmlWriter.Create(sFname, settings)
mySerializer.Serialize(xw, Me)
xw.Close()
End SubThat's the best I can do for you, hope it helps.

Hi We are calling the webservice function from vb script by using "MSSOAP.SoapClient30", the function returns the byte array and we are saving that as *.jar file below is the sample code
============================================================
sAdminSOAPUrl = "http://testapp.com:80/test/ecs/webservices/AdminService?wsdl"
Dim vaData
Set soapClient3 = CreateObject("MSSOAP.SoapClient30")
Call soapClient3.MSSoapInit(sAdminSOAPUrl, "AdminService", "AdminService")
soapClient3.ConnectorProperty("EndPointURL") = sAdminSOAPUrl
vaData = soapClient3.exportDeployment("test","test","test_data")
If (IsArray(vaData)) Then
rgData = vaData
WScript.Echo rgData
sFilename = sPath & "xplbio.jar"
hFile = FreeFile()
Open sFilename For Binary As #hFile
Put #hFile, , rgData
Close #hFile
Dim fso As New FileSystemObject
fso.CopyFile sFilename, sPath & sExportName & ".jar"
fso.DeleteFile sFilename, True
End If
============================================================
now we are trying to use the "MSXML2.ServerXMLHTTP.6.0" instead of "MSSOAP.SoapClient30" but facing issues while writing the response into *.jar file and its being corrupt.
we have tried by channging the respose header as below but facing the same issue
"Content-Type", "text/xml; charset=utf-8",
"Content-Type" "multipart/form-data",
"Content-Type" "application/x-www-form-urlencoded",
is there any thing which I am missing please suggest, below is the sample updated code

For Each Element in NodeList
If Element.tagName = "exportDeploymentReturn" Then
vaData = Element.Text
Exit For
End If
Next
If (IsArray(vaData)) Then
rgData = vaData
WScript.Echo rgData

Good Afternoon,
I have a problem with the focus control(set focus) after showing the dialogs form, can you help me to resolve it ?
Example code:
Private Sub LinkLabel1_LinkClicked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
Form2.ShowDialog()
End Sub
after i show the second form, i can't set focus on a textbox in first form when the second form is closed. i used this code..
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
form1.textbox1.focus
End Sub
Help me please.....Thx

Me.Close()
How do you think the code on this form will continue to run after the statement above?
See Richard Deemings explanation(s)

The code in the same procedure will continue to run, as will any code in the Closing and Closed event handlers.

Yes, but the code in question is not in either of those places.
|
|
|
|
|
Yes it is.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
form1.textbox1.focus End Sub
Calling Close on the previous line won't prevent the second line from executing.
"These people looked deep within my soul and assigned me a number based on the order in which I joined."

That's a button click event, not a Closing or Closed. I just ran a simple test (added a MessageBox.Show after) and although the debugger continued in the method after the call to Close, the MessageBox did not get displayed.

|
|

If you've just closed the last open form in the application, the message box doesn't show. That seems like a bug to me.
If there's another form still open, the message box shows as expected.
Try this example from LINQPad:
void Main()
{
Application.Run(new Form1());
}
class Form1 : Form
{
public Form1()
{
var btn = new Button();
btn.Text = "Open Form2";
btn.Click += btn_Click;
Controls.Add(btn);
}
private void btn_Click(object sender, EventArgs e)
{
var form = new Form2();
form.Show();
}
}
class Form2 : Form
{
public Form2()
{
var btn = new Button();
btn.Text = "Close me";
btn.Click += btn_Click;
Controls.Add(btn);
}
private void btn_Click(object sender, EventArgs e)
{
Close();
Console.WriteLine("Closed");
MessageBox.Show("Closed");
}
}
"These people looked deep within my soul and assigned me a number based on the order in which I joined."
- Homer
|
|
|
|
|
|
Better yet, why is code in Form2 referencing anything at all in Form1?
It should be the job of Form1 to set focus on one of it's controls, not Form2.
Or am I missing something?
|
|
|
|
|
That would be a better solution.

Hello !
I'm using VB.net 2013 and entity Framework 6.
I have a form with a bindingsource.
On the form's load event i have this instruction :
Myobjectbindingsource.datasource=(From t in context.Myobjects Select t).Tolist
I have another event :
Private Sub MyObjectbindingsource_CurrentChanged(sender As Object, e As EventArgs) Handles MyObjectbindingsource.CurrentChanged
Messagebox.show("Hello")
End Sub
If context.myobjects is not empty , before the form is shown , the message "Hello" is displayed 3 times.
My question is why the currentChanged event is called 3 times , because there's only 1 instruction that change items on bindingsource ?
Thank you !
