Hi,
I have finished a project with windowns 2000 profesional and VC++ 6.0. Now i want to run the exe file with different window OS. I really want to know how to make the the exe file run correctly with any windows OS, such as, windows95, windows98, windows ME, windows XP and so on?
Thanks in advance!

If you don't have a PSDK installed, then it will work fine. If you do, then you may find you've used API's not supported on older versions of Windows. If that is so, all you can do is change your code or late bind to those functions and hope none of them are essential ( i.e. then it will work on the older OS', but only if you detect the OS and make sure that code is never run. )

Hi I am setting my dialog based app's position in OnInitDialog() using
SetWindowPos(NULL,0,0,100,100,SWP_NOZORDER);
Unfortuanately this does not work as it places it in the middle of the screen.  If I add 1 to either of the X or Y positions it places it correctly (but out by 1 obviously)
If I use the above code elsewhere in the program its position is correct.
This occurs only in OnInitDialog() so that must be the problem, Any suggestions?

MFC does some additional work during its WM_INITDIALOG handler, after your OnInitDialog() returns. It compares the size/position of the dialog before and after calling OnInitDialog(). If both are exactly the same, it concludes that you have no special sizing/positioning code and calls CenterWindow() for you.

I don't know why I can't figure this out, but can someone please help me change the icon associated with my .exe file?
Not jsut changing the one in the resources because that just changes it on the taskbar, not the .exe.
Any suggestions?
Thank you.

Sorry, it *is* the one in resources. Make sure
- it's the first icon in the .exe (you may need to view the .rc file as text to verify this)
- you're editing both the 16x16 icon *and* the 32x32 icon (they're stored together, Windows loads the correct one) and
- you may need to restart Explorer if it's being obstinant about caching the old icon.

Like Shog said it is the resource one. From what you are describing you have other icons in the project resources. Just ad another copy of your app icon and name it something like 1 so it appears at the top of the list.

When I mix 2 pin-enumerations, a fatal error appears saying that 5 objects are left referenced.
But all interfaces are released properly.
Somebody who knows what's going on here?
HRESULT hr=S_OK;
.
IEnumPins* pEnumFirst=NULL;
hr=(*ppFirst)->EnumPins(&pEnumFirst);
if(FAILED(hr))
return hr;
.
IEnumPins* pEnumSecond=NULL;
hr=(*ppSecond)->EnumPins(&pEnumSecond);
if(FAILED(hr))
return hr;
.
IPin* pPinFirst=NULL;
IPin* pPinSecond=NULL;
.
while(pEnumFirst->Next(1,&pPinFirst,NULL)==S_OK && pEnumSecond->Next(1,&pPinSecond,NULL)==S_OK)
{
pPinFirst->Release();
pPinSecond->Release();
}
.
pEnumFirst->Release();
pPinFirst=NULL;
pEnumFirst=NULL;
.
pEnumSecond->Release();
pPinSecond=NULL;
pEnumSecond=NULL;
...and the pins have to do nothing yet! Afterwards, I want to connect them manualy.

never mind...
should be:
while(pEnumFirst->next ...
{
while(pEnumSecond->next ...
{
...
}

The Task Manager allows you to get a real-time glimpse of the number of processes that are currently running.
Question: Is there an API that allows me to do this (PerfMon?), or do I have to enumerate all the processes after a specified interval?
Thanks,

Hi.
Visual C++ .NET outputs this error when I try to declare a priority queue with reverse sorting.
-----
// Assuming program runs and before I added the following.
#include <queue>
#include <functional>
std::priority_queue<int, std::greater<int="">> m_nQueueList;
// I try this declaration, but receive the exact same
// error everytime.
std::priority_queue<int, std::vector<int="">, std::greater<int>> m_nQueueList;
-----
Here is the error from Visual C++ .NET
-----
C2065: 'm_nQueueList' : undeclared identifier
error C2143: syntax error : missing '>' before ';'
error C2146: syntax error : missing ',' before identifier 'm_nQueueList'
error C2208: '<unknown>' : no members defined using this type
error C2947: expecting '>' to terminate template-argument-list, found '>>'
error C2976: 'std::priority_queue' : too few template arguments
-----
Does anyone know what the problem is?
Thanks,

The first problem that you have is that the < adn > are being destroyed by the HTML parser. When you display code it is a good idea to check the "Display this message as-is (no HTML)" check box when you send your message.
The problem in your code is the >> in this:
std::priority_queue<int, std::greater<int>>
The c++ compiler does not know how to parse the >> symbol if it relates to nested templates. Change your code to this and it should fix it:
std::priority_queue<int, std::greater<int> >

Okay. Thanks.
Added a space in between ">>" fixed it.
Here is the working solution.
-----
std:priority_queue<int, std::vector<int>, std::greater<int> > m_nQueueList;
-----
I would have never guessed the problem had to do with a missing space. That space operator is tricky.

If I add a list box item to a form... How can I get the list control to show a list from values in an access table?
Thanks for your help!

Hmmmm. This can be a lengthy answer so let me point you toi the right direction. I am assuming you are using VC++ 6.0 and by form you mean a dialog of some kind. Even if you are using .Net my answer will not change much.
There is no direct way of populating a list box or any windows control for that matter with information in a database. There are few controls that you can get out there which will accept a recordset as an input. But thats a different story.
To populate a windows control with information in a database, you need to connect to the database, get the data, and provide it to the control. CodeProject is full of examples on how to connect to databases. You should read one of the turorials on ADO and then move on from there.
Hope this helps.

Below is the delcaration of C++ exception class. I cannot understand what a line like this mean:
exception() throw();
Why there are two functions there (constructor and throw)???
Thanks,
Michael
++++++++++++++++++++++++++++++++++++++++++++++++++++++
exception
class exception {
public:
exception() throw();
exception(const exception& rhs) throw();
exception& operator=(const exception& rhs) throw();
virtual ~exception() throw();
virtual const char *what() const throw();
};
|

'throw()' isn't a function. It's a 'exception specification' specifiying which exceptions function is allowed to throw. If function throws exception which is not on the list, C++ calls unexpected exception handler using function called 'unexpected'.
Empty list - 'throw()' means that function isn't allowed to throw anything.

Hello,
I am getting an error during a call to CryptAquireContext.
Here is the code:
if(!CryptAcquireContext(&hCryptProv, NULL, MS_ENHANCED_PROV, PROV_RSA_FULL, 0))<br />
{<br />
HandleError("Error during CryptAcquireContext.");<br />
return -4;<br />
}
This routine works fine on my Win2000 machine as well as another Win98 machine in the office, but our Beta users all get the same error. Is it something I am not registering/not including in the install???
If anybody has any experience with this your input would be appreciated!
Thanks

What about calling GetLastError()?
also, It be because the beta machines don't have the high encryption pack installed.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

I am calling GetLastError() like this:
<br />
void CFPCommonFunctions::HandleError(CString strFunction) <br />
{ <br />
CString strMsg;<br />
strMsg.Format("CFPCommonFunctions::EncryptTransFile() - %s: %u.", strFunction, GetLastError());<br />
AfxMessageBox(strMsg, MB_OK | MB_ICONEXCLAMATION);<br />
}<br />
This returns 80090019, but there is no corresponding code in the Windows error table. I think I am not formating this message correctly.
Also, what do you mean by "don't have the high encryption pack installed"? The documentation on MSDN says that it is compatible with Win95 OSR2 and up. It relies on advapi32.dll, which these users have installed and registered...
Is there something I am missing???

In the project I work for, every time we have problems with the Crypto API is because the host don't have the high encryption pack installed (since we are using high encryption).

I have a CDialogBar derived object attached to the bottom of my MDI mainframe window. Works fine, except it is left justified in the frame/bar...I want it centered in the frame.
How do I do this?
I have tried overriding the OnWindowPosChanging and setting the position that way...which moves the window ok, but leaves garbage to the left of the window.

Try with void DockControlBar( CControlBar * pBar, UINT nDockBarID, LPCRECT lpRect) but specify lpRect for size and position, nDockBarID is ... well I guess you get the idea!

i develped an app, it has been used by customers for over 2 months (at least 16 hrs a day - for machines) with no problem, but i still warry about it, really need ur suggestion.
my question is:
in the app, i used a large buffer, some code as following:
//the large buffer, iSize>100,1000
char*pszBuf=new char[iSize];
char*p0=pszBuf+100;
char*p1=pszBuf+1000;
char ch=*p1;
*p1=0; //key point to warry, temp break the string
CString cs=p0;
*p1=ch;
in this way, access can be in high speed, main app uses in the way always (say, once/50 ms).
there are 3 threads use the buffer at same time (read only) and access whole buffer.
at first, i thought there must be troubles because i broke the buffer with *p1=0 and other threads can't access whole buffer. but after 2 months, no any problem!
in theory, i need to lock the buffer while doing break, but it is too complicated to do so.
why no problem? am i luck or OS helps me to do something i don't know?
thx.
