Im a newbie when it comes to .Net technologies. Right now I am developing an MDI application using VB.Net. So this is my first .NEt project.
first question:
... why is that when the child form is being closed using the control menu (control box), the next time i click the menu item that should make the child form show up again, it won't show anymore?....
here's the code behind the menu item:
Private Sub mnuRR_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuRR.Click
If RRChild Is Nothing Then
RRChild = New frmReceivingOrders(Me)
End If
RRChild.Show()
End Sub
* RRChild is the child form
* mnuRR is the menu item of the parent form
... tnx
.. here we go again.
|
|
|
|
|
This is how I've opened my MDI child forms.
Dim RRChild as New frmReceivingOrders
RRChild.MdiParent=Me
RRChild.Show()
Hope this helps
Cheers
PL

We have a project that we recently split from one very large exe into 5 DLL projects. We have a greate deal of classes in each of the projects and we find that when we compile the program on a dev box there is a period shortly after the compile is completed where the app hangs for about 10-15 seconds.
Another of our guys had the same problem when at another site, where, once they had a large number of classes, VB was doing the same thing?
We have T30 and T40 IBM notebooks, so the processors and memory are fine, has anyone else experienced this and can anyone suggest anything?
Cheers,
Andy

My guess, if this is a .NET project, is that it is the initial JIT compilation that you are seeing.

Another possibility is that the IDE is re-registering the .DLLs. (REGSVR32)

I'm trying to consume a C# Web Service using VB6 and Soap Toolkit 3.
Everything works fine when I'm passing/returning simple data types such as strings and integers but I'm having trouble using complex data types.
The class I'm trying to pass is defined in my C# WS as
public class AlertMessage
{
public string AlertMessage;
public string AlertComment;
}
How do I treat this in VB and how do I pass it?
Currently, I have created an ActiveX DLL with a class AlertMessage as follows:
Private mAlertText As String
Private mAlertComment As String
Public Property Get AlertText() As String
AlertText = mAlertText
End Property
Public Property Let AlertText(ByVal Value As String)
mAlertText = Value
End Property
Public Property Get AlertComment() As String
AlertText = mAlertComment
End Property
Public Property Let AlertComment(ByVal Value As String)
mAlertComment = Value
End Property
When trying to pass an AlertMessage to the WS I get the following error:
SoapMapper: Saving SoapMapper alertMessage failed. No such interface supported.
When trying to return an AlertMessage from the WS I get a type mismatch error. My Soap response looks as follows:
<?xml version="1.0" encoding="utf-8" ?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<GetAlertMessageResponse xmlns="http://star-navigation.com/webservices/">
<GetAlertMessageResult>
<AlertText>Hello There</AlertText>
<AlertComment>My Comment</AlertComment>
</GetAlertMessageResult>
</GetAlertMessageResponse>
</soap:Body>
</soap:Envelope>
Can anyone help?
Thanks,
Cory

Am learning VB. I have not had the need until recently to install one of my apps on a machine that doesn't have VBruntime installed. Is there a way to include vbruntime in the install application so that it installs on the users machine at the same time as the application I have created?
Thanks,
Jim

Hi!
I have a problem with the center of the form in relating to the changing of the screen resolution and I would like to have aide. Please help!
In my application, I change the screen resolution to 800x600 when the app is started and will restore to the original state when quit. About the code of changing the screen resolution, it like the code in the sample of the www.AllAPI.net: http://www.mentalis.org/apilist/ChangeDisplaySettings.shtml
My problem is that if I change the screen resolution and then in my app, I use a procedure to center the form like this:
Sub centerForm(ByRef theForm As Form)
theForm.Left = (Screen.Width - theForm.ScaleWidth) / 2
theForm.Top = (Screen.Height - theForm.ScaleHeight) / 2
End Sub
but I always have a problem that the form nerver be centered correctly
I case I don't change the screen resolution, I don't have this problem
This is the thing that I would like to need you help
Thanks in advanced!

I've never looked at this one myself, but you might give it a try:

I have tried to figure something out that I want to write in code, but I couldn't find the solution. Until now. I found the following piece of code on the Internet today. Unfortunately, it is in the language of C (I think so), a language that I don't know anything about. So, I would be very grateful if anyone could translate it to Visual Basic code.
<br />
#include iostream.h<br />
<br />
int fak(int n);<br />
<br />
void main()<br />
{<br />
int x=5;<br />
<br />
cout<< x << "!=" << endl;<br />
cout<< fak(x) << endl;<br />
cout<< 5*4*3*2*1 << endl;<br />
}<br />
<br />
int fak(int n)<br />
{<br />
if (n<=0)<br />
return 1;<br />
<br />
else<br />
{<br />
int a = n*fak( n-1 );<br />
return (a);<br />
}<br />
}<br />

(Untested and VB.NET, so replace Integer with Long in VB6)
Function Factorial(ByVal n As Integer) As Integer
' AFAIK, you can actually do this as <= 1 instead
If n <= 0 then
return 1
else
return n * Factorial(n - 1)
end if
End Function
You might want to read up on recursive functions, as that is all this is.

So there is a function to do n-factorial. I didn't know that. Well, I was hoping to find out how to write a for...while loop or something that does the same thing. I have spoken with my mathematics teacher and we are trying to find some algorithm to do n-factorial. I mean, a calculator doesn't know what, for example, "5!" is, does it? I tried to write a loop with "counter" that added "1" for every loop, and when "counter" had the same value as "n". It did not work, though.
But thanks for the help, anyway.
