Can you give more details on what you're trying to achieve Cathy? I'm a little unclear what you mean by "but the script re-enables it".
The other thread is trying to determine if they have a valid license. I don't want them to be able to use the program for a certian period during the validation. Our program is a COM server. If I disable the main window, the scripting engine reinables it.

However, if EnableWindow() isn't cutting the mustard for you and you just need to prevent menu/toolbar activity, selectively trapping CN_COMMAND messages in an OnCmdMsg() override in the mainframe might achieve what you need. Remember to let CN_UPDATE_COMMAND_UI calls through though or your toolbars etc. won't update properly.
Thank you. I will try that.

Try using a mutex/WaitForSingleObject to pause your main thread. Then from the thread that verifies that they have a valid license, close the mutex, thus allowing your main thread to continue.

Unless I'm missing something that will still prevent the UI from painting during the checking process.
Good idea in all other respects though!

Trouble with resource IDs? Try the Resource ID Organiser Add-In for Visual C++ 5.0/6.0

Good luck Cathy. OnCmdMsg() is a useful (and damn scary at times) thing to mess with.
If you get stuck, shout and I'll post some examples.

hi
1) how can i get the names of the columns in a table without creating a CRecordset. I get the tables form the MSysObjects table. Maybe there is an other way to get the tables?????
I work with a Access databases, SQL and use the ODBC drivers.
2) is there a way to change the rights (read, write..) in C++ without using Access. Maybe through the ODBC driver????????????
please help!!!!!!!!!!!!!
Thx

hi,
anyone know how transfer datas from the Main Dialog to a TabPage?
|
|
|
|
|
you can do a GetItemDlg(IDC_OBJECT) to retrieve a pointer on the data structure. You have to cast the value like (CEdit *) GetItemDlg (IDC_EDIT);

I'm having a strange problem that I'm hoping someone can shed some light on.
In my COM server (.exe) i invoke the CString method Format. The problem is execution goes to the wrong override! Then it blows up.
Here is the initial command:
[ccode]
strDiag.Format(("iTotalUnused * 100) / g_ThreadsArray.GetSize() = %d",iTotalUnused * 100) / g_ThreadsArray.GetSize());
[/ccode]
When this executes I trace it into:
[ccode]
void AFX_CDECL CString::Format(UINT nFormatID, ...){ CString strFormat; VERIFY(strFormat.LoadString(nFormatID) != 0); va_list argList; va_start(argList, nFormatID); FormatV(strFormat, argList); va_end(argList);}
[/ccode]
instead of
[ccode]
// formatting (using FormatMessage style formatting)void AFX_CDECL CString::FormatMessage(LPCTSTR lpszFormat, ...){
[/ccode]
The actual blowup occurs in the LoadString function (which I don't want called in the first place0. It calls AfxGetResourceHandle which asserts afxCurrentResourceHandle is NULL.
I don't believe this is a bug in the CString class (i've used it too many times in this program.) I don't see anything wrong in my code, unless its environmental:
This control is windowless, it launches some number of worker threads and assigns tasks to them as requested. This code runs in one of the worker threads. The threads are created by instantiating a CWinThread derived object and invoiking its CreateThread method.
Thanks for the help,
Bill

The problem was caused by a typo,the parentheses are off.

Seems like the evil comma operator strikes back
Well I guess all the problem reduces to having your first quotation mark displaced to the right of the second parenthesis, instead than to the left. As it stands, your expression evaluates as follows:
strDiag.Format(
(
"iTotalUnused * 100) / g_ThreadsArray.GetSize() = %d",
iTotalUnused * 100
) / g_ThreadsArray.GetSize());==> (operator , evaluates to its second argument)
strDiag.Format(
(
iTotalUnused * 100
) / g_ThreadsArray.GetSize());==>
strDiag.Format(iTotalUnused * 100 / g_ThreadsArray.GetSize()); and this of course selects the Format(UINT,...) overload.

I have an byte array that contains 24 bit image. I would like to be able to scale it using StrechDIBits or something similar before I save the "compatible bitmap" to a bmp file. The problem is that if my screen is 16bit then my compatible DC is also 16 bits when I want it to be 24 and my image turns out distorted. Is there anyway to make a DC that is 24 bits even if the screen is at another BPP?
Please Help,
Clint Singer
PS. I thought I would try CreateDC but it seems that DEVMODE is only good for printers.

I don't know, but I *do* know if you create a DIBSection you can make it 24 bit and stretchblt it in a DC of any bpp. You could create one the same size and copy the bitmap data into it, then viola.
If you find a way to create a DC with a different bpp, I'd sure be interested to hear about it.

Do you have any examples as how to do this as I haven't been able to work well with a CreateDIBSection. I also assume one wouldn't use CreateCompatibleBitmap but rather define the Bitmap and all it's attributes to be 24bpp.
Thanks,
Clint

I would if www.wdj.com would come up. If you download the code for Sept 2000, I had an article there in which I create DIBSections and copy bitmaps onto them.

How do you make a program that is split up into two parts? Like this
-----------------------------------------------
///////////|
///////////|
///////////|
///////////|
///////////|
///////////|
1//////////|2
-----------------------------------------------
How do I make that?
If I put one line of text in 1 that is there forever how can I make it open a .txt file in number 2?
Can someone help me?

I'm sorry, This happens a tipical question of a guy that wants that us make his homework.
Your question is serious. I was confused by your graphic...
You need to use Splits.
For this you need to use two views, look for splits into codeproject you will can find a couple of good articles talking about splits.
I'm Sorry again....
Best Regards...
Carlos Antollini.

Where can I find the split articles? I can't find them.

Nevermind that last post, but I don't understand how to make them in Visual C++. Can anyone help? If you help can you make a step by step "tutorial"?
Also I am sorry for asking this. It is just that I am a complete rookie and my english isn't that great.

You can find articles on Splitter Windows here. I think this is what you're looking for.
Also, I recommend buying a reference book if you're serious about programming. While not entirely necessary, books can be quite helpful. Click here for a list of useful reference books.
Good luck!

You don't have to apologize. I can understand that you would think that way. I would have thought that way if I was good at C++ and a 15 year old boy asked you to help him with a program.
Now the problem. I can't understand which one I should use. What would be the easiest one for me to use to make the diagram I want?
I am sorry if I am bugging you.

Okey:
I think that this article is very good for start.
As soon as you understood that article, you will can continue with this Article.
At the finish you will be an expert in Splitter window.
I Hope to see an article about splitter window written by you in the future
Best Regards!!!
