Hi, I need help using Crystal Report into a MFC Application.
Can Somebody describe the main step needed to use a CR Viewer,show a Cr report and set a Selection Formula?
I'm able to show a simple report, but i'm not able to set a Selection Formula so I think I use in a wrong way the ActiveX.

P.S. I need extremelly this help.. please!!! Sigh | :sigh:

I have just seen this article, but it isn't helpfuls because it's refer to Visual C++ 6 and steps described don't fit in Visual Studio 2005, for example I haven't CCrystalCtrl and CRowCursor ActiveX.

Who can help implement this in Visual Studio 2005... it's very important

Thanks

I found for a lot of time in the internet but I wasn't able to obtain what I need. D'Oh! | :doh:

I hoped you and your team can explain me which step I must perform to use the ActiveX, view the report and set new Selection_Formula in Visual C++, on Visual Studio 2005. Sigh | :sigh:

Thanks a lot for your interesting.

Differences between GetWindowRect and GetClientRect???

Hi,

Could anybody tell me what is the differences between GetWindowRect and GetClientRect?

Thank you

MSDN :
GetWindowRect(): The GetWindowRect function retrieves the dimensions of the bounding rectangle of the specified window. The dimensions are given in screen coordinates that are relative to the upper-left corner of the screen.
GetClientRect(): The GetClientRect function retrieves the coordinates of a window's client area. The client coordinates specify the upper-left and lower-right corners of the client area. Because client coordinates are relative to the upper-left corner of a window's client area, the coordinates of the upper-left corner are (0,0).

Somethings seem HARD to do, until we know how to do them.

So,GetWindowRect is to get the window rectangle and client rectangle is to get the boundary of any control over the window???

Are you asking that GetCientRect(..) can be used to find the rect position of child control(windows) in the mail window??..

If so its not like that..
Simply you can put it like this....

GetClientRect(..) will give the window position and size with respect to itself (as stated earlier, always left and top values will be zero) and the right and bottom value will be equal as its width and height.

GetWindowRect(..) will give the window position with respect to screen area.

Say for example... your screen resolution 1024x768. You have a window whose upper left corner starts at the center of the screen and its width and height are 100 and 50 resp, then...

GetWindowRect(..) will return this - left = 512, top = 384, right = 612 and bottom = 434.

GetClientRect(..) will return this - left = 0, top = 0, reight = 100 and bottom = 50

Hope this will help...

The main algorithm for ZIP file compression is called 'Deflate' and is documented here[^]. Zlib[^] is a free implementation of the Deflate algorithm.

If you want to use the ZIP archive format as well, the libzip[^] library is often mentioned. I found it not particularly easy to use, so when coding something that needed to unzip a compressed archive, I used the ZIP file specification[^] and a few hints from the libzip source code for how to invoke the Inflate algorithm.

Stability. What an interesting concept. -- Chris Maunder

Hi all ,
I m using Worker thread in my application.
i am passing a char neha[260] value to my thread
and after passing it i again want to convert it from LPVOID to char neha[260]
can anybody tell me how to perform conversion.......
When i m writing
s8_Buf = *(static_cast<char*>(pParam));
Its Giving an error
error C2440: '=' : cannot convert from 'char' to 'char [260]'

can anybody help me in this....

Thanks in advance

error C2440: '=' : cannot convert from 'char' to 'char [260]':

char *p=static_cast<char*>(pParam); // This should work
How are you declaring s8_Buf in your code?

Hi
s8_Buf = *(static_cast(pParam));

char s8_Buf*; //Better Use TCHAR for MFC
s8_Buf = (char*)pParam; //Try to avoid this type of coding
or
s8_Buf = static_cast<char*>(pParam); //This will work fine
//IN the above statement insett less than symbol after static_cast then char* then greater than symbol ,next to that (pParam) follows....

Dynamic Multidimentional Array?

MohammadAmiry12-Mar-07 1:11

hi I need to have a 2D or 3D array in VC++, I use the following code:
<pre><code>
float** aa;
for(i=0;i<m;i++)
aa=new float* [m];
for(i=0;i<n;i++)
aa[i]=new float [n];
</code></pre>

to create an m*n matrix. But sometimes it throws Access Violation error.
I want to know if there is any better way to do this?

Re: Dynamic Multidimentional Array?

Modify this to,

float** aa =new float*[m];//take this outside
for(int i=0;i < m;i++)
{
aa[i]=new float [n];
}

and while accessing it use this loop,

for (int i = 0 ; i < m;i++)
{
for (int j = 0 ; j < n; j++)
aa[i][j] = 0.0;
}
}
