First, void* pMsgBuf; has been declared but not used. I think you should use pMsgBuf instead of the lpMsgBuf[BUFSIZE]; because the flag: FORMAT_MESSAGE_ALLOCATE_BUFFER causes memory to be allocated to the buffer, which you should deallocate using LocalFree(...);
And use FORMAT_MESSAGE_FROM_SYSTEM instead of FORMAT_MESSAGE_FROM_HMODULE.
Hope that helps.
this is this.

Hi,
Thanks for the reply. I had a LPVOID lpMsgBuf declared which i was using (not seen in posted code).
The reason I have used FORMAT_MESSAGE_FROM_HMODULE is because I have my own custom HRESULT codes defined in the mc (message compiler file) and their corresponding messages.
FORMAT_MESSAGE_FROM_SYSTEM only displays the system defined messages ..
and E_FILESAVED is a custom-defined message defined in mc file as follows:
<br />
MessageId = 2000<br />
SymbolicName = E_FILESAVED<br />
Language = English<br />
File Saved Successfully!<br />
Thanks!

You can take the contents of the newly-created .RC file, and place them in the .RC2 file for example. That should help. If you don't have a .RC2 file, then place the text directly in the .RC file.
this is this.

In the description of SetWindowText(), it states that "it cannot change the text of a control in another application". Does anyone know how to do this, given the handle of the window control ? Thanks (in advance !!)

It shouldn't be possible to write to another application's textbox because your text buffer is located in your program's address space, not their's.
You can check the following article:
http://www.codeproject.com/threads/winspy.asp[^]
There are other articles as well.

Thanks Khan++ for your reply,
The article that you referenced is going to take "some reading" !! I DO hope that there is some way to write to another app's controls as otherwise my current idea is "stuffed" !!!
Any other replies/suggestions to my problem would be welcomed !!

As per SetWindowText documentation:-
"To set the text of a control in another process, send the WM_SETTEXT message directly instead of calling SetWindowText"

Hi Vipin,
I use VC++ Ver 6.0 and can't see this statement in SetWindowText(). What version do you see it in ?

Just checked MSDN and I DO see that statement - why doesn't 6.0 include it ??
Anyhow, great relief, as the other possibilities are pretty complex !! Thanks everyone !

Hi I have a problem.....
Actually i wrote a code which runs in service and hides in tray icon when minimized or closed...
When iam testing it by executing, its working , after when i restart the system to make run in service..
It is visible in service ,But No tray icon is Visible
If i keep any message Box in OnCreate() function ,
Then it's Working ...
Please help me...............
Thanks in Advance

I think it is because the service runs before any user is logged-on to the system, so when the serivice is setting its icon, the system tray has not been spawned yet.
I would suggest that you reset the tray icon every minute or so, so that it can be seen. Also, if explorer.exe crashes, all icons disappear. If you reset your icon every minute or so, your icon will remain in the tray.
this is this.

Try making the service Interactive service.

Actually, I used a class from here in my BugReporter[^]app to aid in putting the icon in the system tray. That worked great! But I also got the problem that when Explorer crashed and came back up, my icon was no longer in the tray. I can't remember off the top of my head, but you can register a message that will notify you of when the system tray/taskbar is being re-instantiated or redrawn. Handle that message and then redraw your icon. I think that's better than checking every minute. If you'd like to look in the BugReporter project, I think it's in the CMainFrame class that I did this.

For that you have to create Desktop interactive service.. you have to do that by two way :-
Manual Way:-
Right Click on Service-> Choose Properties menu item-> then when Property Sheet get displayed-> choose Log On Tab-> check Allow Service to interact with Desktop check box.
Coding Way:-
while installing service using CreateService api pass SERVICE_INTERACTIVE_PROCESS as one of parameter

I think it depends on who you are building it for. If the client is stupid, and thinks .Net is new and hence better, then create it in .Net. However, I think un-managed apps will have problems with it. (Not sure). And I am not sure, even if it is possible to support the things you need. .Net is new, and you won't find (m)any experts in it.
If on the other hand, you are serious about creating the control, that is easy to use, easy to modify, can be controlled to the finest of details, is real-fast, then go for Un-managed. And you can get help from the Gurus if you ever get stuck.
1- It can contain web-browsers, if you need them.
2- It can contain buttons, list boxes, etc.
3- Can adjust its position, size.
4- Can support drag-drop. (Not sure how .Net apps will behave to that).
this is this.

Hi to everyone. I write data to a file without problems using CFile and CArchive classes, but the data write in a single line in the file.1) I want to be able to change line in the file. For example, the record Last Name, First Name, Hobby, Age should write in one line.The next record (which append) should become in new line, as it appears delow:
DeliyiannisDimitrisReading23 (First record in the file)
PapadopoulosJohnBasketball20 (Second record in the file)
... ... ... ...
... ... ... ...
2)Ηow can I access diffirent records? For example, if the user enter John OR Papadopoulos OR Basketball OR 20 in an edit box then in diffirent edit boxes display Papadopoulos John Basketball 20.
Please, help me. Thanks.

1-
If you writing data in the form of text to a textfile, then you can append "\r\n" to every line.
However, if you want the same program to read back the records, then you would be having problems, because you would have appended "\r\n" Carriage-return + Line-feed pair to the data yourself.
2-
To read the records back, read the file line by line like using CStdioFile::ReadString(...). Then parse the text yourself to obtain the values.
this is this.

I think COM will be the way to go as far as designing is concerned. I think that when you are actually designing the form, that "un-named language" IDE is actually running the form in some way.
Create an MDI project, then the rest will be COM work; like resizable controls at runtime etc. Even the form itself will be resizable.
If I had to do it, I would start writing the controls; starting with the form, then the other controls.
And in which form do you want to save it? That "un-named language" IDE saves forms as binary files. So you will need to do some research on its format.
this is this.

Can a ANSI-C compliant compiler compile successfully a code containing functions embedded in structure?
hitherto shall thou come but not further thee
|
|
|
|

I think C does not support functions in structs. But in C++, structs and classes are very similar, and both can contain functions.
So for a .C file, functions within struct will not compile.
