Hi,
Share all your Windows Application using this...

Hi,
Windows application programs are EXE files for DOS and Windows systems. An EXE file is an executable file, which is a file in a format that the computer can directly execute and are not easily read by humans. Executable files for Windows and DOS systems have an.EXE extension.

Hi,
The way of using Windows application is user friendly.we can just drag and drop the Controls from the toolbox instead of coding.

Hi,
The language specially designed to help developing Windows application is Visual Basic. And now it is Visual C#.

The very important tool to program in Windows is VC++.

The API is the very important concept in Windows Programming.

The acronym of API is "Application Programming Interface".

The API is used to interact with the OS directly. The languages such as VB will call these APIs indirectly. In VC++ the APIs will often be called directly in our program. We can also call them in VB.

The APIs are the means for the Applications to communicate with the OS.
For example we are justopening a form in VB or a window screen in Word or anything simply. But on the background the Application corresponding to the task of opening the window will call the CreateWindow() function from the Operating System.

The createwindow function requires 12 paramenters and it will looks as

hWnd = CreateWindowEx(WS_EX_TOOLWINDOW,
ClsName,
WndName,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL);

Thus a simple event in windows is possible only after a complicated job in the behind

Hi,

i m getting this error while i want to overwrite the existing file.

ImageCodecInfo usedIC = this.GetEncoderInfo("image/bmp");
Encoder encoder = Encoder.Quality;
EncoderParameters encparams = new EncoderParameters(1);
EncoderParameter encparam = new EncoderParameter(encoder, (long)100);
encparams.Param[0] = encparam;
test.Save("C:\\cute1.jpg", usedIC, encparams);//Error


In this coding only i m getting this error. test.Save("C:\\cute1.jpg", usedIC, encparams);
I m already saving the image as bmp in this path.Again taking tat bmp image rotating it and then saving it like this.
plz tell me the best solution

Hi,
I solved tat problem by opening the image using FileStream.
I deleted the existing file and created the new one with the same name.
This overcomes the problem.
Any other solution?Plz post here.

For most of Visual Basic's history, you did not need to specify you were building a rich-client application—all the applications you built were rich-client apps. Web development has never been the purpose of Visual Basic. This focus on developing stand-alone or client/server applications with a Windows user interface created a very tight bond between the VB language and the forms engine within it. There was no need to distinguish between the language and the tools for building an interface in VB6, but there certainly is in .NET.
