Thanks for the replies guys,
If anyone is interested, I have also found that you can check the LockCount member of CRITICAL_SECTION to see if a thread is already in the critical section.
LockCount == -1 if the critical section is not already in use e.g.
if(lock.LockCount >= 0)
{
TRACE("Locked\n");
}

Hi All
I have to create a GUI in turbo C++ for Dos.
and I want to give Windows like look in interface.
so can you please tell me any library for GUI which could be used in DOS.
or tell me any better approach.
Thanks

Use Borland C++ 2.0 (or maybe 3.0). It comes with TurboVision. I believe 3.0 could produce oth Windows and DOS apps.... it's been over 15 years since I did a DOS app...

 Humm, this seems Hard to do with TurboC++.
See here for some help[^]
Somethings seem HARD to do, until we know how to do them.

Thanks U all
OK I will start to write such programs
can u please guide me how to proceed
But would like to tell the reason whiy I need ..
Infact working on such project where if system is crashed then system will be started with a bootable floppy ( in DOS mode) and our application will be invoked so wanna write GUI code for that part..
Please help me
Thanks

Telling you how to write an application is WAY beyond the scope of this forum.

Isn't that called Windows 3.0?
More seriously, when I did DOS programming, there were several graphics libraries, UI toolkits and other such things available. Unfortunately, not only are the obsolete, most the companies don't exist any more. (I last evaluated one of these libraries in 1989--the name "GreenLeaf" pops into mind--if they are who I remember them to be, contact them and see if they have some archived stuff they can sell you.)
A big problem is finding products that actually have drivers for DOS (this was the big bugaboo when doing this; you had to ship with a ton of graphics drivers and hoped that the user knew which one they were using since there was no standard detection method [somewhere, I have the code to detect if you were running Hercules mono, CGA, EGA or VGA graphics.])
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Unfortunately, modern support for the 'old' video standards is hit-or-miss. I've got an old text-mode DOS app that my company uses in manufacturing. We've got a shrinking pile of old hardware that gets swapped around and periodically refurbished for the app to run on. I've not had good luck running it on contemporary hardware. BIOS functions are missing or incorrectly implemented, hardware register emulation is half-assed, and so on. I get the impression that, about ten years ago, someone wrote a 'text-mode emulator' package in VHDL, and everyone's been using it since then without ever testing it.
Yeah, I know it would be smarter for me to rewrite the app. It's a lot cheaper, however, to have a technician scrounge up some hardware every six months and spend half a day putting it together.

I need to get a list of all the Bluetooth Devices that the PC is paired with.
We make a Bluetooth device that my code talks to as though it were a COM Port. All the paired devices appear in a list in 'Bluetooth Devices'. At present my user has to pick a com port from a list of 1 to 256. It would be alot better to tell them what device is connected to which COM port and let them pick from that list.
I haven't a clue where to look, and Googling gives me loads of results, almost all of which are at a much less detailed level.
Any ideas anyone?

Does anyone know how to communicate with a web server through 2-way SSL (https) from an MFC app using the clients default browsers certificate store? I have to make an app work that uses a variety of browsers (Netscape 7.2, IE, and Mozilla Firefox) certificate stores to communicate with a WebLogic server.
Any help would be greatly appreciated.

how to concatenate strings with longs for example if i want to do that:
long j=5;
MessageBox("the number is"+J+"apples");
|
|
|
|
|
You can use printf for that:
char szBuffer[50];
sprintf(szBuffer,"the number is %i apples",J);
Take a look at sprintf[^] and format spec[^] in the MSDN for more details.
|
|
|
|
|
See CString::Formatand wsprintf(...)
|
|
|
|
|
Also you can use CString class as,
CString str("");
LONG l = 5;
str.Format("The Number is %ld Apples", l);
MessageBox(str);

I have a SDI program that uses ScroolView. If I put only 25 lines of text everything it's ok but if I put out 250 lines then it won't display it all. I know I can set the scroolsize with SetScrollSizes in the OnInitialUpdate() function. My question is : can I modify that scrool size throughout the program?
|
|
|
|

tanarnelinistit wrote: My question is : can I modify that scrool size throughout the program?
Yes of course.
BTW, why didn't you test it ? You just have to add two or three lines of code and you'll get your answer
|
|
|
|
|
By the way: it's 'scroll', not 'scrool'.

I already have a imageList and would like to use images from it as input to the CMenu SetMenuItemBitmaps. But I can only see how to get an HIcon from CImageList and I can't find out how to convert it to a bitmap (or any other way for consumption by CMenu).
Thanks for any help!!

Use GetIconInfo(..) API to have HBITMAP from HICON...
ICONINFO IconInfo;
GetIconInfo(hIcon, &IconInfo);
then use IconInfo.hbmColor for HBITMAP...
i.e., HBITMAP hBitmap = IconInfo.hbmColor;
Make sure to delete those bitmap handles as..
DeleteObject(IconInfo.hbmColor);
DeleteObject(IconInfo.hbmMask);

First of all, posting your entire application and asking someone to finish it for you isn't going to work. We're here to answer questions, not complete your application for you.
Second, when you post code, either use the <pre> tag, or make sure the "Ignore HTML tags in this message (good for code snippets)" check box is checked.
Try asking a more specific question. Since you said you have been working on this 'for days', start out by telling us what you tried, and why it didn't work.

I m the beginer in the world of VC++. I m like a 1 month old baby in this world of VC++.
I want ask u all a very basic question ie. how to call an already created dll in ur code.
I m actually developing an interface between AutoCad n SAP.
AutoCad provides runtime extensions called ARX.
Object-ARX is an API and they r a kind of dll's which r to be used to programm ur Autocad Appllication.
So start with this project of mine I very first need to understand how to use dll's in ur code.
Plssssssssss somebody on forum who knows the answer reply me
waiting for a reply
