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.

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.

Hi all, I need some help. I'm trying to draw to a device that does not really have a device. The resolution for this device is 204x196. An application that someone else did takes all the positions of the objects/texts and multiplies them by a factor. Unfortunatly, with this factor, I cannot get text to line up as I can on the screen and the printer. He is using a factor of 2.12, but this does not equate to one inch on the screen to one inch on the new device and to one inch on the printer. Actually, 2.18 equates to one inch. (This factor does create fonts in the correct position.)
What I was thinking was to do one of the following:
- Use the SetWindowExt/SetViewportExt -- didn't work...
- Create a expansion of one above that will allow perfact scaling then get the bit map and shrink it down.
- Use the ScaleViewportExtEx and just magnify it up to the proper scale. I cannot seem to get this to work as advertised.
So, any help that you guys can give would be greatly appericated.
Thanks

Some thoughts would be to do one of the following:
Figure out why the ScaleViewportExt is not working.
Do double buffer drawing and simply do a StretchBlt rather than a BitBlt when drawing to your scaled device. This approach doesn't always look very good, though.
onwards and upwards...

How does the WindowExt & ViewportExt work? I know they have no effect on map modes like MM_LOENGLIDS/MM_HIENGLISH/MM_LOMETRIC/MM_HIMETRIC/MM_TWIPS/MM_TEXT. It only has an effect if you are using MM_ISOTROPIC and MM_ANISOTROPIC. By using these you can create a one-to-one relations ship with other units?
Like: The screen is usally 96dpi and I have a device that is 200dpi. I create a bitmap in 200dpi (lengthXwidth), then use these to create a conversion from the 96 -> 200?
Examle:
pDC->SetMapMode( MM_ISOTROPIC );
pDC->SetWindowExt( 96 * 8.5, 96 * 11 ); // or 120 if using large fonts
pDC->SetViewportExt( 200*8.5, 200*11 );
Rect( 96, 96, 192, 192 );
pDC->Rectangle( &Rect )
Would this create a 1" x 1" on the new bitmap?
Thanks

Hi,
I am programming with Visual C++ 6.0. My sources files are on an intranet network. Visual C++ is installed locally on my computer. I compile and link over the network.
I plan to put my sources files in my desktop computer and compile locally because I have remark that compiling true the network is slow.
I want to know wich method is using to back up sources files at the end of the day.
Bye,
Claude

I know what you mean. Even a 100 TX connection is slow during compiles. I think this is mainy because of permissions but I may be wrong...
I created a batch file to zip my source and copy it to the network folder.
