Thanks for the reply. I included the code from the link you gave me and tried to create a CMainWindowIterator. However, the compiler complains b/c it doesn't recognize the EnumProcesses and EnumProcessModules functions from his code. MSDN lists these other the "psapi.h" header, so I tried including <psapi> and <psapi.h>, but the compiler for 6.0 didn't recognize these either. These appear to be .NET dlls? How can I use this for 6.0?
Thanks.

No. They work fine with v6, but you'll need the Platform SDK first.

I got a hold of the psapi files, and everything compiles fine in Debug mode. Except the window doesn't stay on top of the other app (it behaves as any other window). Here's my code:
DWORD appPID; // the pid of the application I want my app to stay on top of
CMainWindowIterator wndIter(appPID);
HWND appHwnd = wndIter.First();
CWnd * pAppCWnd = FromHandle(appHwnd);
SetWindowPos(pAppCWnd , 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
Also, when I build in release mode, I get the following warning:
LINK : warning LNK4089: all references to "PSAPI.DLL" discarded by /OPT:REF

Hi there,
I wish to make my edit control accept only capital letters in combination with numbers. The member variable (m_confirmation_num) for that control is a CString with max characters of 5. That string later gets converted to a UINT conf_num. Initially m_confirmation is set to NULL and m_conf_num to 0. The edit control is defaulted to "00000" when the dialog box is first opened. With CAPS LOCK on or OFF, the edit control accepts only capital letters. This is what I want but why does it do that. This only happens with the following set up but for cases where I do not want the zeroes to display in the field, it accepts lowercase.
Is there a way to make the edit control accept only capital letters? Or have the lowercase changed to uppercase upon user input? And is there a function that checks to see if a char is uppper or lowercase? Thanks.

see in the edit box properties in design editor...

|

Duh. I've looked at the properties but somehow overlooked it. Thanks a lot!

One solution is WM_CHAR message.

I suppose it could just be that the line.length is reporting the length of the line with a newline and carriage return character stripped out, but the tellg is "telling it like it is"

Put the call to tellg() in the for loop to know for sure.

I have been scouring the web, msdn, and the help files trying to figure out how to do this, and have gotten nowhere except a web of abstract articles on Active Directories, and I'm not really sure A.D. is what I need to use to do this.
 Can someone please point me in the right direction?
Thanks in advance for any help you can give.

Extra Details, just in case they're relevant:
I'm using DAO to access a database on another computer on the network, which fails if the local machine does not already have an open connection to the server computer. I'm looking to check for the connection before opening the DAO object, and create the connection if it's not connected.
I have serviceable, though not pretty, methods for checking the connection, but have no idea how to create it.)

To simplify the process, this is the code snippet to open a DB that uses the default system database (usr/pass db).
#include <afxdao.h>
CDaoDatabase* daoDB = new CDaoDatabase();
try {
daoDB->Open("\\\\Main\\E-Drive\\DB\\Operational.mdb", false, true);
} catch (CDaoException * daoE) {
return false;
} catch (Exception* e) {
return false;
};
if (!daoDB->IsOpen()) {
return false;
};
Thanks again,

So what exception is thrown, or what error do you receive?

The daoDB->ReportError() method reports:
The Microsoft Jet database engine cannot open the file '\\Main\E-Drive\DB\Operational.mdb'.
It is already opened exclusively by another user, or you need permission to view its data. If, however, I open My Computer and type '\\Main\E-Drive\DB\' (or any valid path on \\Main) in the address bar, it prompts me to enter my user/pass, and then displays the contents of the drive/folder.
After doing that, if I run the program again, I will no longer receive the error message and the DAO engine can access the file without issue.
(It also works if I map a network drive to some share on \\Main .)
My problem is that I can't seem to find a way to programatically connect to \\Main so that the share can be accessed.

Would is be acceptable to call NetUseAdd() first to map a drive letter to \\Main\\E-Drive, and then use that drive letter in the call to Open()?

I don't know how none of my searches turned that up, but thank you. I pulled up NetUseAdd in the help file, and the first thing (ok, second thing) it says is that you don't have to actually map the drive - you can use it to just authenticate with the server for future transactions. This should be perfect!
Thanks, Mr. Crow - what a great help!

Hello,
I am using an user defined List Control in my application. (CXListCtrl provided by Mr. Hans in Code Project).
If any other window (whose size is less than the size of Control size) is placed and removed that area is not repainted. When I checked OnPaint () of the implemeentation of control is left for default by calling Default () function. I tried to replace Invalidate () before that but it goes for indefinite loop as Invalidate () also invokes OnDraw function.
I tested by invoking a notepad making the size of it less than the size of List control, place it on top the control and switch back to my application. I find the area of notepad being blank. Placing some TRACE Message I found that OnDraw () function of the control is called when i do that test. But since Default () function is called it is not painting that area.
Can any one suggest me what can be done to avoid the repainting problem?
I am developing an MFC SDI application in .NET environment on Windows XP.
Thanks for your Time

Hi I am building a client/server application based on TCP/IP. The Server is running and client can connect to it. Now I want to show a Folder Dialog on client that lists the contents of Server. The client needs to select a folder on Server.
Anyone with suggestions? code examples?
thanks
Adnan

Imho, the appropriate way to do this is for your server to support a request that lists the contents of a folder under its control (much like an FTP server, a nice sample of which can be found here[^]). The client app will make requests off the server as and when it needs to expand a folder in the tree control displayed to the user.

Hi Friends
Do u have any idea for comparing two bitmaps images . Any code in c /c ++ ?
thanx in advance 
|
|
|
|
|
What do you want to do ? Can't you simply check if each pixels are equal in both images ?
|
|
|
|
|
Cedric I think that this isnt a good way but possible that he check for each pixel in bitmaps in a loop(only a for)
but usually width and height aren't equal
so 1-first create a bitmap in screen that width and height are same(800x800) and draw bitmap in this screen also for bitmap2
then in one loop read pixels from bitmap1 and bitmap2
Is it possible?
|
|
|
|
|
I don't think the problem is defined well enough for any kind of reply. Do the bitmaps have noise? Like, for example, the ones that come from a live camera? Or are they synthetic (computer generated)?
What does the comparison try to obtain? The diferences? In which form? In the form of a diferential image? Or in the form of a list of diferene regions and their bounding boxes, for example? Or does the comparison result in a flag that says something like "image 1 = room empty", and "image 2 = intruder detected!!"?
