Hello,
How can you change the size of the MDI container in a MDI parent form?
|
|
|
|
|
The control is MdiClient. You just need to enumerate the Controls collection of the form, looking for a control of Type MdiClient. Then you need to turn off the Dock proeprty and set the position and size properties to whatever you need.
|
|
|
|
|
Is this the way you mean,but it's not working.When maximize the parent form,the child form maximizes to the entire form.What is the problem?
For Each ctrl As Control In Me.Controls
If TypeOf ctrl Is MdiClient Then
ctrl.Dock = DockStyle.None
ctrl.Location = New System.Drawing.Point(1, 107)
ctrl.Size = New System.Drawing.Size(769, 434)
End If
Next

That code works fine and as expected, though I'd probably add an Exit For before the End If.
If you're saying that the title bar for the child form takes up the entire width of the patent form, this is the expected behavior and you can't turn it off.
If you're saying that if you maximize the parent form and this causes the child form to maximize also, then something in your code is causing this. The code you posted will not do cause that problem to happen.

Hi,
I want to initiate a uninstall process of an application (already install) through another vb.net application.
Is it possible?

Yes. It can be done using the Process class.

Hi.
i have 2 applications. one developed in c# and other in vb 6. vb application makes some changes to sql database. These changes need to be recorded in another database(used by c# code). Due to privilages on the databases, i need vb to call the c# exe and provide it with 2 arguments. That is, my vb code needs to call a C# exe and provide it with two arguments. C# application is a console application. is this possible in vb. If yes, some help would be greatly appreciated.
Thanx in advance
mark

I am not at all sure that you can call into a managed .EXE from VB6.
However, if C-like exports between VB6 and VB.Net[^] is correct you can call into a managed .dll. If you are able to separate the parts of your application to be called into a dll and apply the principles from the article to it, that might be a resolution to your problem.

Hi,
thanx for replying.
I went through the article you forwarded, and realized that it requires editing in IL. I also read some comments and other articles and am confused whether i should take this approach or not?
If you can provide some more help, i would be really greatfull . Thanx

Hi,
you probably could organize the C# app as a console app taking its parameters from the command line; and invoke it the way VB6 invokes all EXE files, through some magic function (system? ShellExecute? I don't recall).
FWIW: if the parameters become more complex, I tend to have the master EXE put them in a file, and pass the full filepath (which would contain numeric date and time to make it unique) as the single parameter to the slave EXE.

Hi,
Thanx for replying.
I have received a reply that points at the fact that "vb might not be able to call managed dll/exe". which is the case in .net. Do you still think that i should organize the C# application as console and invoke it using vb6 shell. Again, being a .net programmer, i would appreciate if u forward me a better link on system? ShellExecute? .
Thankyou again

.DLL:
do what Uncle said above to make the .dll support interop. Make sure you to use generic data types in your method signature. There are plenty of tutorials on this. Use regasm as nec on clients, etc.
.EXE:
You can start a .Net exe from VB6. For a simple example, all you have to do is something like:
strRunFilename = strRunFilename & " " & gstrCommandLineProgram
Shell strRunFilename, vbNormalFocus
Note that gstrCommandLineProgram get parsed from within the .Net .exe and the appropriate action(s) are taken. You could also use CreateProcessWithLogon, WaitForSingleObject, etc, etc depending on exactly what you need to do; but shell is easy and probably suffice for you what you're trying to do.
This is digging deep in the memory banks, but I think shell will work pretty much for any OS level where as CreateProcessWithLogon may have not worked with win98 (if there are OS requirements).

OK, I am in the home stretch here, dynamic context menu over dynamic control arrays, for a guy new to .net. I have it all working except for one small, strange little thing. In my procedure to show the context menu, I thought I could just use the me.mouseposition. as follows:
Private Sub lblSlot_click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Click
HandlePopup(sender, e) ' build my menu
Debug.Write(Me.MousePosition())
ContextMenu1.Show(Me, Me.MousePosition)
Debug.Write(Me.MousePosition())
End Sub
if I look at the output in the debug window pre and post clicking the mouse and seeing the popup, I will see something like the following: The menu does not pop up near where the mouse was.
{x=786, Y=476}{x=797, Y=687}
any idea what may be going on here?

What is the .Net equiv to this vb6 format:
Format(strCode, "@@-@@@@-@@")
Apparently my brain has stopped functioning today. Sigh.

Thanks for the reply.
I've tried String.Format and MS.VB.Format without the results I expect. Is the @ character no longer supported?

I think your problem is that the parameters have switched round, and yes it is no longer "@" it is now "{0}". See the MSDN Documentation[^]
Try :String.Format("{0}{0}-{0}{0}{0}{0}-{0}{0}", mycode)
If I understand correctly, if your code was "g" you want the result "gg-gggg-gg". .Net supports multiple replaces in the format string hence the use of "{0}"

Correct on the desired output. I understand the string.format in regards to the {number} format, which is just a place holder for text. I just thought there would be something a little prettier than this type of scenario:
'To get a @@-@@@@-@@
Dim h As String = "23snfg33"
Dim result As String = String.Format("{0}{1}-{2}{3}{4}{5}-{6}{7}", h.Chars(0), h.Chars(1), h.Chars(2), h.Chars(3), h.Chars(4), h.Chars(5), h.Chars(6), h.Chars(7))
The format literals I have found deal directly with numeric or date outputs, not with just plain old character place holders.
No big whoop though, thanks for input.

Just to pretty it up a bit, you could do:
'To get a @@-@@@@-@@
Dim h As String = "23snfg33"
Dim result As String = String.Format("{0}-{1}-{2}", h.Substring(0, 2), h.Substring(2, 4), h.Substring(6, 2))

I have a much better solution, having slept on it. Use a System.ComponentModel.MaskedTextProvider. To make it easier wrap it up in a Class. e.g.
Public Class MaskFormater
Private Sub New()
End Sub
Public Shared Function Format(ByVal input As String, ByVal mask As String) As String
Dim maskProvider As New System.ComponentModel.MaskedTextProvider(mask)
maskProvider.Add(input)
Return maskProvider.ToDisplayString()
End Function
End Class
This can then be used as follows:
'To get a @@-@@@@-@@
Dim h As String = "23snfg33"
Dim result As String = MaskFormater.Format(h, "aa-aaaa-aa")
For a list of available masking elements see the mask documentation on MSDN[^]">
