Your post is a little confused.

Do you want to populate each form with data from the matching database table or do you want to select data from multiple tables and display in one form?

Which Database classes are you using? CDatabase? ADO?

I recommend you use ADO, which you can use your ODBC connection with.

Have a look at these classes[^], as they'll make it easier.

ROP Problem

Hi!

What I get is a HDC with some stuff on it and all I have to do is draw a string over that like watermark. This string can be anything of any color and any angle.
After my drawing the resultant is a Postscript output.

Now I am drawing watemark string with ROP2 MERGE_PEN but the string is always on the top and the data below is hidden. Where as I want this string to be transparent so that every thing is vissible.

I have tried with different ROPS but the result is same.

One more interesting I found is
If I draw with Hatched brush then O/p is OK although it is hatched but is transparent but if I draw using Pattern Brush then it is not transparent.

Pls. let me know if there is some another way to draw a transparent text.

Thanks

Well I dont prefer to use GDI+. Customer may not have it...
It will be great if you can suggest some way using just windows API's

Anyways I would still like to know how to do using GDI+ just for my knowledge...

Thanks

Draw the text on black and then use TransparentBlt ?

In GDI+ you can set the transparency of a solid brush, which you'd then use to draw the text.

So does that mean to make a bitmap with text and black background and then do TransparentBlt on original DC?

Well, then that won't work, I guess. You'd have to do it somewhat more manually, as in byte by byte.

I'm not sure if this is what's causing your problem, but you might try setting the background mode to transparent before drawing your text:

// yourHDC would be the HDC you are drawing to.
int prevBkMode = SetBkMode( yourHDC, TRANSPARENT );
 
// Do your text drawing here.
// ...
 
// Restoring the background mode to it's previous value is good form, of course.
SetBkMode( yourHDC, prevBkMode );

I have already done that ...my problem is not with the background of text.
Background is transparent ...but the letters are not transparent...
Where the letter is drawn the text below it is hidden.

Life Cycle of Window Service is manage by ServiceMain function, it is entry point of service like main() for dos based c++ and WinMain for Win32

you can communicate via Interprocess communication because service is also a process

Control services by using the service functions such as StartService.
You can send some control commands to a service using the function ControlService.

Dear All,
I'm trying to add an ActiveX Control to the dialogs in my ActiveX Control Project. The problem is that I'm unable to drop the ActiveX control from the Controls Toolbar, to a Dialog in my project. I get the following error:

"Cannot drop ActiveX controls in Non-MFC dialogs."

Is there any other way i can do this?

Devoirs,

IP address box

i want to implement non-MFC based IP address box.
i tried the following as advised by Alok when i posted the mail earliar.

i tried to implement the IP address using the following code

hWnd = CreateWindowEx(NULL,ClsName,WndName,WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, 300, 200, NULL, NULL, GetModuleHandle(NULL), NULL);

HWND IPAddrWindow = CreateWindow("SysIPAddress32",NULL, WS_VISIBLE|WS_CHILD,35,55,250,30,hWnd,NULL,NULL,NULL);

But the IP Address box is not created... only the blank base window is displayed. where am i wrong?

thanx in advance

Where is the code, if necessary, to create the four edit controls? They are child windows of the "SysIPAddress32" window.

How about calling:

iccex.dwSize = sizeof(iccex);
iccex.dwICC  = ICC_INTERNET_CLASSES;
InitCommonControlsEx(&iccex);
