Hi
I know this is a C++ forum but i think this is a very common question.
I am creating a client server application in VB.net. client is calling a method in the server using a proxy class. I am throwing an exception on the server side. Now i want the client to capture that particular exception. How can i do that. I could able to achive this when i run both client and server on the same machine but when i run the client on the different machine I am getting an exception server generated and exception check the server's config. file. How can i catch the particular exception generated by server.
thank you

how can i make a SDI application into full screen, in a way that application occupies entire screen(no taskbar )and no Minimizing/moving for the window..

Consider making it a dialog based app and removing the dialog's caption bar at design time. Then, in the dialog's OnInitDialog() handler call SetWindowPos() to maximize the window and keep it on top of all other windows.
PS: This won't cover the taskbar.

Hey Ravi, Thats not a dialog based app..
that s a SDI app.

you can do the similar thing for the sdi application too.. in the onCreate event remove the caption style before the frame is created.

I have implemented 2 threads simulating the counting semaphore. One thread sleeps for 20 milliseconds as in Sleep(20);
The other thread writes the time into a file. When i observe the file, in my System it prints for 50 times/second, which should be the case (20 milliseconds * 50 = 1000 milliseconds = 1second).
In other computers, it writes only 32 times / second in the file.
What could be the problem.?

that might be beacause windows is not a real-time kernel. so, if an application is running in kernel mode, even if your interrupt signal must call your asynchronous function, that one will have to wait for the process running ends its part.
So, using such functions is not precise if you want your event to process each n seconds. prefer an interrupt handler.

That you are relying on Sleep(), and assuming that time is consistent between computers, especially if they are running different OSs. Read this article on why time is not always accurate.

Hello
I am working on a MFC SDI application.
On My one of the menu i am drawing something with the CDC which is Memory dc and is drawing in a bitmap.
Above mentioned CDC MemDC is global.
Now on Save
I am having two Options
save content of CDC to JPEG and
save as BMP.
Well I am using implementation fo ImageHandler (from Codeguru) so it works fine. With JPEG saving. It does uses the CDC for putting into JPEG image.
Now with BMP saving, previously i was using CDibSectionLite (from Codeguru) using the above Bitmap. I want to use CDC instead because of change in the design.
Is there any other way to save content of DC directly to the Bitmap file
Thanks in advance.

Hi there,
I'm a bit new to C++, been doing Java for a while now and I was just wondering if there is a way to get the 'Start Button' to appear as an entry in the context menu that appears when you right click on the desktop, if not any suggestions on how I should go about it?
Cheers,
/P/

First of all, i consider u r familiar with the VC++ IDE.
So, first of all, add a "Resource Script" to ur project. Then insert an MENU into it. Add a few feilds to the menu and give it a "DENTIFIER STRING".
Then to display a CONTEXT MENU u hav 2 write:
IN MFC:
void CMenuTestView::OnRButtonDown(UINT nFlags, CPoint point)
{
CMenu myMenu;
CMenu *ptrMenu;
myMenu.LoadMenu(IDR_MYMENU);
ptrMenu=myMenu.GetSubMenu(0);
ClientToScreen(&point);
ptrMenu->TrackPopupMenu
(
TPM_LEFTALIGN|TPM_RIGHTBUTTON,
point.x,
point.y,
this,
NULL
);
CView::OnRButtonDown(nFlags, point);
}
IN WINDOWS API:
case WM_RBUTTONDOWN:
POINT p;
GetCursorPos(&p);
TrackPopupMenu(GetSubMenu(LoadMenu(gloInst,"MYMENU"),0),
TPM_LEFTALIGN | TPM_LEFTBUTTON,p.x,p.y,0,hwnd,NULL);
break;

Hi!,
I want to create a read-only view of excel,word or powerpoint file using the ole techonology.
I use the default object handler provided in ole32.dll
I dont know what steps to follow after creating the object using:
hr=CoCreateInstance(clsid,NULL,CLSCTX_INPROC_HANDLER,
IID_IUnknown,(PVOID*)&pUkwn);
the object handler basically implements IDataObject,IOleCache and IViewObject.
IViewObject::Draw will draw on the specified device.
but before that I want to pass data to the object.
which interface shall I use?
thanks

Im getting this error in a project Im working on, its referencing a .cpp file with function definitions, Im using the same .h & .cpp file on their own just using a main.cpp to test it and it works fine, but when I brought it over to the larger project I get this error:
fatal error C1010: unexpected end of file while looking for precompiled header directive.
I checked the MSDN library and it was of absolutly no help whatsoever, I dont know what it even means. Im using VC7 with win2k.
Cheers

arf, i've already seen that error, and i've got abslolutely no idea about its cause.
To avoid that, check Your project settings and disable the precompiled headers... it will work.
if anybody know about the reason this error occurs, let us know !!

put #include "stdafx.h" at the top of the file.
Or, go to project->settings and select the file. Go to C++->Precompiled Headers and set it to "Not using precompiled headers"
|
|
|
|
|
Your larger project is setup to use precompiled headers. This allows you to setup a set of include files that are used through-out your project and have them compiled just once. This is normally done by including the required headers in stdafx.h. Then when compiling the project VC++ expects stdafx.h to be included at the start of each .cpp file.
Just add #include "stdafx.h" to the start of the new .cpp file.

Someone asked me this question this morning - and I didn't have an answer. Can anyone explain why it is bad to use a macro function?
Dylan
|
|
|
|
|
because there is no controle on the parameters passed to it. second reason, we are obliged not to separate the macro name and the opening parenthesis '(' that follow it, which is not very practical.

Only in the macro's definition, not its usage.
