Hi Friends,
I need to show zoom combo box in print preview window like Microsoft power point print preview.
I removed zoom in and zoom out buttons.
I dervied my class i.e.
class CPrintPreviewView : public CPreviewView
{
void SetScaledSize(UINT nPage);
}
void CPrintPreviewView ::SetScaledSize(UINT nPage)
{
switch(m_nZoomState)
{
case ZOOM_25:
pRatio->cx = 25
pRatio->cy = 100;
break;
case ZOOM_400:
pRatio->cx = 400
pRatio>cy = 100;
break;
}
}
I inserted the zoom combobox and added zoom levels from
25% to 400%, as user selects value in cobmobox, I update zoom ratio and call DoZoom function.
But there is some calculation problem.... ??? I dont know what ??
But if i keep zoom in & zoom out buttons and click zoom out button once
and then use combo , there is no problem.
Everthing is fine.
Can you please provide me some code snippet.
Thanks,
Subhash Madhukar

There is a bit of guessing going on here, but I would think that the OnSelChange for the combo box would need to call:
SetZoomState(requiredZoomLevel, 0, CPoint(0, 0));
where requiredZoomLevel maps to the the correct zoom level of:
0 for totally zoomed out
1 for next zoom level etc...
If you vote me down, my score will only get lower

MSDN says
For the TB_THUMBPOSITION and TB_THUMBTRACK notifications, the high-order word of the wParam parameter specifies the position of the slider. For all other notifications, the high-order word is zero; send the TBM_GETPOS ( GetPos ) message to determine the slider position. The lParam parameter is the handle to the trackbar.

can anyone please tell me how to create the message digest using openssl library in linux....
????
|
|
|
|
|
Looking at the documentation for MD5 in openssl[^], it looks like it's as simple as calling the MD5 function:
const char* msg = "This is my message";
unsigned char digest[MD5_DIGEST_LENGTH];
MD5(msg, strlen(msg) * sizeof(char), digest);

Thanx man...
I did it but that method is a bit long using the evp.h

As the title suggests I'm having a problem compiling MFC based applications, this problem started immediately after installing the windows server 2003 platform SDK and now even when I try to compile a new MFC project I get the following errors:

in some cases I solved the problem by including/moving windows.h and defining WIN32_LEAN_AND_MEAN at the top of stdafx.h. However for large projects that uses static and dynamic linking to other libraries the proposed solution did not work. I'm not really sure why this is happening as I've also tried to reinstall the platform SDK to no avail.
Any help is appreciated.
Thanx

Check the vc++ directory settings( Tools->options->vc++ directories ) of visual studio. if it contains path from SDK folder, remove it.

I would if I don't want to use the SDK...

Whats is that SDK 2003 has and VS 2005 dosen't...?
|
|
|
|
|
I need to use Icftypes for firewall controlling which is only available in platform SDK 
|
|
|
|
|
Well in that case you have to download the latest SDK 
|
|
|
|
|
I would try a repair/reinstall of VS 2005 through Add/Remove Programs.
The platform SDK installer can change some paths or configurations and it may be faster to just do the repair than to try to track down a few changes.

Please never do this.
Read the article suggested by Rajesh (or BSTR documentation [^]) to discover why.

Hi!
I have ATL Webservice (SOAP or DIME Webservice ) already hosted on IIS.
IT is perfectly working from past 10 years. no issues.
Already we are using SOAP SDK on client side.
Now We need to use MTOM on client. Actually All our components are in C++ with out .net framework.
I need a solution to use MTOM on C++ without .net framework.
Please suggest me

I wonder if someone can help me understand why, when I made changes to the following code worked (more like, gave me the result that I wanted) and if I did something wrong which can come back to haunt me later on (don't bash me  )
Original Code:
CFileDialog fOpenDlg(true,NULL,NULL,NULL,_T("All Files (*.*)|*.*||"),this);
CString fName = NULL;
string name;
fName = fOpenDlg.GetFileName();
name = fName;
Error: error C2679: binary '=' : no operator found which takes a right-hand operand of type 'CString' (or there is no acceptable conversion)
now the Modified Code (not the final one):
CFileDialog fOpenDlg(true,NULL,NULL,NULL,_T("All Files (*.*)|*.*||"),this);
CString fName = NULL;
string name;
fName = fOpenDlg.GetFileName();
name = *fName;
Observation: if I open a file named test.txt fName gets set to test, and name gets set to t
Final code (giving me the result I wanted, discovered accidentally while applying it elsewhere):
CFileDialog fOpenDlg(true,NULL,NULL,NULL,_T("All Files (*.*)|*.*||"),this);
CString fName = NULL;
string name;
fName = fOpenDlg.GetFileName();
name = (fName+"");
Observation: now if I open a file named test.txt, fName gets set to test, and name ALSO gets set to test. I've been wondering how that +"" changed the behavior
Thanks

Are you doing a Unicode or an ANSI build?! This works for me, and I am doing a Unicode build.
std::wstring cppStr;
CFileDialog cfd(true);
if(cfd.DoModal()==IDOK)
{
cppStr = cfd.GetFileName();
wcout<<cppStr.c_str();
}
I hope you can figure out your mistakes.
Also, I don't understand why do you need to use std::string if you're already using MFC. Why not use CString?!
