Re: Microsft Visual Studio string tables with Similar Strings

This looks very interesting. I have never used AFX_MANAGE_STATE(AfxGetStaticModuleState()) before. I am not useing LoadLibrary() anywhere in the projects. I just put the library location in the linker of Microsoft Visual Studios 6.0. Also I wonder if AFX_MANAGE_STATE would even work because the description of this macro is "Call this macro to protect an exported function in a DLL." I am not sure if this would work with a library or not.

It very well may not. Your problem just sounded like one that the macro was designed to resolve (e.g., a DLL and an EXE both having a like-numbered resource, but the wrong one gets loaded).

Creating a bitmap viewer in Visual C++

Does anyone know of a sample MS Visual C++ program that takes raw black and white video data (saved as a binary file) that is transmitted at 3 frames/sec and shows them on the screen at the same rate?

if not, is there an article that explains how to do this in Visual C++?

thanks in advance.

Seems you can control the frame rate manually by extracting each of your frames from the movie data.

If (1) your "black & white video data" is actually "8-bit grey-scale" (which is what one might expect from a video camera), and (2) the image size is fixed (number of pixels horizontal & vertical is known), it could be quite easy.

Create a window to use to display the images
Create a bitmap header.
Set the bitmap parameters (number pixels X & Y, pixel depth, not using pallette, etc)
Read the binary file into some area in memory
Set the bitmap header "data" parameter to point to your data
Use SetDIBitsToDevice to display it in your window.
Repeat the last 3 steps until stopped

If the video has unusual attributes (for example, it is 12-bit greyscale from a medical imager, or if it is in columns not rows) you will probably need an intermediate step, to create a bitmap which Windows understands.

Hi all,

Ok, this may sound like i'm repeating myself, but does someone know how to validate just the username on the domain, to check if it is a valid username found on the domain.

I know about the funcion logonUser(), but the function doesn't work without a password parameter.

Plz help

Thanx

User is able to open a file by double clicking in middle of two columns of ClistCtrl

hi,
i hv a small problem...i m using ClistCtrl, and to launch a file open user has to double click..now even if the user clicks on the white portion where name of file is not written, still the file is opened. reason being that the ItemRect is the complete Rextangle and if the size of name of file is say 2 chars then the rest portion is white in the Bounding rectangle, but when clicked the item is identified and the file opened. for the user it becms difficult if there r multiple columns n hence he thinks that the area between the columns is white so does not belong to the item...
Can anyone suggest me a way out....

Thanx in advance..

Use CListCtrl::HitTest(..) with LVHT_ONITEMLABEL flag

the flag is a out parameter and you have check the flag as (LVHT_ONITEMLABEL & flag)

WM_KEYDOWN

Hi, I saw in one application,i debuged that.
When the control goes to SendMEssage(WM_KEYDOWN,49,0) in one class after executing that class the controls goes to OnKEyDown() in another class,there they pass that
Case 49:
CString Str + ="1";

I dont know how the controls goes to that class automatically..for that particular WM_KEYDOWN.
It may be a silly question but i need that.
I am going to do this in my appl.

Win32 API to check for a process state

We have a function GetModuleBaseName(...) which gets the process names which are running currently in our system by putting it in a loop. From that we get the name of the process and we can check that name with our process name and know the status.

IMHO CreateToolHelp32SnapShot() can help.
To enumerate the heap or module states for all processes, specify TH32CS_SNAPALL and set th32ProcessID to zero.

Somethings seem HARD to do, until we know how to do them.

Create a member variable(of type int) for the first Radio button. so when u call
UpdateData( TRUE ); u will have the checked radio buttons index in that variable.

Instead of comparing CButton::GetCheck() with 'true' use BST_CHECKED or BST_UNCHECKED.
