I am Using VS.NET 2003. I tried dragging Activex controls
from toolbar to the form.
It does the following things
1. Creating tlbimp wrapper file and it is sucess.
2. Creating Aximp wrapper file and it does something after
that it poppedup "File or assemblyname Axinterop.ID.dll or one of the depencies was not found". (Note:ID is activex name)
I tried even with command prompt
1. tlbimp abc.ocx /out:interop.abc.dll and it created sucessfully
2. aximp abc.ocx /out:axinterop.abc.dll /rcw:interop.abc.dll /rcw:interop.stdole.dll
AxImp Error: File or assembly name stdole, or one of its dependencies, was not found.
Can any body faced this type of problem?
(Note: Even Microsoft activex control also giving the same problem?  )
Please tell me some method to use Activex control in .NET
Thanks,
Uma Mahes

You have to do custom drawing, I guess, because you need to have DC.
Look at ::GetTextExtentExPoint or ::GetTextExtentExPoint
|
|
|
|
|
CDC* pDC = GetDC();
char szTmp[256];
edt.GetWindowText(szTmp);
int nSize = pDC->GetTextExtent(szTmp).cx;
//and now simply compare the edt width with nSize;

I have to develop an application that manages a double network interface.
This means that the target PC is equipped with 2 network cards with different
IP address.
My application must be able to manage both cards, to send data over both
networks and to distinguish data received from one or the other card.
How can I solve this problem ??
Thanks a lot!

If you're using sockets, you can create one socket for each IP address, and then whatever is received is available through that particular socket.

can anybody tell me something different between WM_CTLCOLOR and =WM_CTLCOLOR
in mfc?

The WM_CTLCOLOR message is used in 16-bit versions of Windows to change the color scheme of list boxes, the list boxes of combo boxes, button controls, edit controls, static controls, message boxes, and dialog boxes.
If an application processes this message, it returns a handle to a brush. The system uses the brush to paint the background of the control
=WM_CTLCOLOR
In classwizard WM_CTLCOLOR will appear as "=WM_CTLCOLOR"

This has to do with subclassing of controls. I really can't elaborate that much on the topic because I have used it only once and I hardly remember it, but go to MSDN and search for subclassing.

WM_CTLCOLOR is the Windows message sent to the parent of a control.
MFC allows the control itself to handle some messages that are actually sent to its parent. This is called message reflection, and WM_CTLCOLOR is one of these messages. If you handle WM_CTLCOLOR in a particular window (eg. myWindow), then you handle a message sent from one of myWindow's children. If you handle =WM_CTLCOLOR, you handle a message that was sent from myWindow to its parent.
I hope this is clear enough to understand

my regular dll is dynamicly linked to my application.the regular dll is built using the dynamic_link library version of mfc while the application is built using the static_link library version of mfc.
when i call AfxGetInstanceHandle() in my regular dll.it caused severe error.
then i rebuild my application using dynamic_link library version of mfc.it is ok.
i wonder if i must use dynamic_link library of mfc in my application when the
application calls a regular dll.

not necessarily. It could be std itself. Check /MD, /MT compiler flags.

hi everybody
i used int system("...") function to execute a command .now i don't know if it is possible to read the result of the command and store it somewhere.
reading the line using cin is impossible before that execution terminated.
if it is possible using ShellExecute please help me.

The output in command prompt can be redirected to a file this way:
app.exe > outfile.txt
Parse the file to get the output. I hope this helps.

Hi folks,
I have a problem with my application.
I'd like to debug a program with an Graphical User Interface with some buttons,Edit bix etc...
This project call a Dll, where inside it there is a COM object with its methods and interface, it's placed in another project.
so,I register this component with Component Service (Control Panel/dministrator tools/Component Service.
When I tried to debug my GUI, happens that the new Visual Studio application is loaded but unfortunatly appear only an assembly windows and in a workspace windows only a DllHost.exe.
After that the VS assembly windows is complete blocked and the complete application crashed. 
Someone,do you know how to debug component out of process or can tell me where I make a mistake?
Thanks in advance for your answers..

Hi !
I got the problem with subject:
For document backup application there is a driver i use,
this is a virtual printer. When a user prints to this printer,
it must see a window with some information. All work well if this is a single user environment, but in Terminal Services user don't see a window,
because a driver has a SYSTEM user, not that user on some terminal session,
that's why window is always shown on server.
How i can fix this problem ?
Best regards, Stas

I know the simple and easy way on how to create a context help file. For each dialog resource I just have to add the ID of the dialog (actually the ID created by makehelp) to the rtf file. The problem is that I have a dialog which I use over and over but its contents are different depending on the menu (or the button) that calls it. Therefore, I have different help topics that need to be associated with the dialog. The problem is that the dialog has only one ID and I don't know how to associate it with different topics.
For example I have a button called "Category" and when I click it a dialog pops up with a bunch of data in it. The idea is that if I hit F1, the "Category" help topic will appear on the screen.
I have another button called "Items" and when I click it the same dialog that I used for "Category" pops up but this time it contains another set of data. Therefore, F1 should display the "Items" help topic.
The problem is that the dialog has a unique ID which I can't pass to the help file because I can associate this ID only with one topic. Any suggestions please?

Use CDialog::SetHelpID() to set different help IDs based on the data you are showing.
