In Vb, I would have an option or groupbox, with checkbox controls on it. I could set a value for each checkbox and then write the following code...
Select Case optGroupbox1<br />
<br />
Case 1: 'checkbox 1<br />
'statements<br />
Case 2: 'checkbox 2<br />
'statements<br />
End Select
How would I implement the above code in vb.net?
I've tried the following but vb.net does not like Case chkbox1.CheckState = CheckState.Checked call...
Select Case GroupBox1.Controls<br />
<br />
Case chkbox1.CheckState = CheckState.Checked<br />
'statements<br />
End Select
Thanks in advance.

VB.NET won't work like that. Since you've specified GroupBox1.Controls in the Select statement, you can only specify properties of the Controls collection, not it's contents.
You'll have to enumerate the controls collection to get this to work:
For Each gbc As Control in GroupBox1.Controls
Select Case gbc.Name
Case "chkbox1":
If gbc.CheckState = CheckState.Checked Then
...
End If
End Select
Next

while savinf the DTS package with visual basic file and converting it into vb.net file i get troublews how do i convert vb6 file to vb.net?
|
|
|
|

Recode it by hand. I have no idea what's your trying to say about DTS, but converting the VB6 code by hand is the best method.

Open the VB6 projects .VBP file in Visual Studio and it'll launch the Conversion Wizard. I highly recommend not doing this and just rewriting the project from scratch though. The conversion doesn't do a perfect job of converting code and it will NOT take advantage of any improvements made in the .NET Framework or VB.NET language. It'll generate code that emulates and is functionally equivilent to VB6, but that's about all.

VB.NET = VB.NET2003. VB.NET is an identifier that covers the language versions 2002, 2003, 2005, and above.

Hi,
I am trying to write a sub-routine in a VBScript to split a file path into 3 bits.
For example I want to split the following path:
"C:\Program Files\MyProg\Studio\win32\bin\filt.exe"
into 3 bits:
1. C:\Program Files
2. \MyProg\Studio\win32\bin
3. \filt.exe
The First part will always be de-limited by 'Program Files' (or the 2nd '\').
The Second part will be delimited from the end of 'Program Files' to the last '\' in the path.
The 3rd Part will be delimited from the last '\' to the end of the path.
The source of the initial file path is stored in an input file, and the split path is to be stored in another text file in the following format:
"C:\Program Files" ** "\MyProg\Studio\win32\bin" ** "\filt.exe"
I hope this is clear, and someone will be able to assist. Any help will be much appreciated.
Thanks

This is simple string handling.
You can use the FileSystemObject's GetFilename method to get the last part of the string.
You can use WScript.ExpandEnvironmentStrings to get the path to the Program Files folder (which is NOT always on C:!!). All you need to do is exand the environment variable "ProgramFiles" and it'll usually return C:\Program Files.
After that, it's simple string handling to get the middle part. Hint: What's the length of the strings returned by both of these calls?

Hi all,
I'm modifying an application written in VB6. I need to show into a dialog some data that is correctly stored in an Access 2003 database. The texts stored are written in Slovenian and when I use the Adodc::Recordset to retrieve them and show into the dialog they are shown badly.
Anybody knows what I should do or what I'm doing wrong?
Thanks in advance,
Marc Soleda

I have some text boxes in a form.On leave event of the textbox control, I am validating the
values by pop uping the message.When I press the ESC or Cancel Button,I need to close
form.When the focus is on textbox control and the textbox is not empty on that time I am
pressing ESC button, that validation message is pop-uping.I need to avoid that pop up
message.

Don't put the code in the OnLeave event. Put it in the TextBox's Validating[^] event and set the TextBox's .CausesValidation property to True. Check the documentation for an example.

Hi,
while programming quite robust application in VB.NET 2.0 a minor problem occured when the application is closing it sometimes "forgets" to remove itself from the bottom bar (there are no exceptions thrown, by clicking on it it simply disappears - which is obvious as the application is already closed). I remember that this was a problem in c++ too but it was removed by slight modification of events posted when the application was closing. I am quite surprised this happens here, where these events should be completely managed. The only closing event I am using for application purposes is just 'FormClosing'. Others I expect to manage by themselves.
Can someone tell me how to remove this flaw and properly close the application ? Thank you.

It's usually still there because you're forgotten to dispose of (release) either unmanaged resources or managed objects that hold onto unmanaged resources.

I have an application which connects to internet.After connecting to the net a new toolbat appears in main window.from the toolbar we activate a child window.I think that application coded in C++.My question is Can we access the child window through our code in vb.net please suggest books/readings

Define "access that child window". If you're talking about just casting that window to a Form object in VB.NET, then no, you can't do that. The only method you have is sending Window messages to each of the controls on that form. It's a very cumbersome process to find the correct window handles for each of the controls you want to "talk" to and sending/retrieving data. There is no "easy" way to do it.

Toolbar also has events MouseDown and MouseUp.
Toolbar's buttons have event ButtonClick.
I think that's all you need.

hello, i have called the function OleCreatePictureIndirect correctly in Vb6, but after upgrading to VB.Net, the calling of the function doesnt works.
with the returned message,
no argument is given for parameter "lpPictDesc" from "Private Function OleCreatePictureIndirect(lpPictDesc As ADV.modWindowing.PictDesc, riid As ADV.modWindowing.Guid, fPictureOwnsHandle As Integer, ipic As Object) As Integer" (translated from german-version, maybe not exactly)
by the way, i didn't change any parameters for it by calling the function. does anyone can help me to solve the problem?
thx

Hi guys,
I'm loading a bunch of combos on my form.
because their are so many items to load, this takes some time to perform.
What tricks can I use to speed this up?
I've tried doing it in a seperate thread. (by the time the user has filled in the first textbox, the combos are loaded), but MSDN's explanation isn't very clear to me.
I also tried to set the combo's CheckForIllegalCrossThreadCalls property to false, but then I get some exceptions (Nothing helpful though).
I found an article here on CodeProject on threadcalling, but I'm working in VS2005 which reacts much more difficult to calling controls in other threads...
Does anybody have some advice about this issue for me?
Thanks a lot!
I've found a living worth working for, but I haven't found work worth living for.
