I have a problem using CDateTimeCtrl. When I choose a date using the DatePicker, the OnChange function associated with the CDateTimeCtrl was called twice, but if I enter a date using the keyboard it was only called once. I hope you could help me on my problem.

can any one tell me wat are all the major advantages of Memory DC plz..
Thanks,

By using a Memory DC you can prepare the image in memory and then in your WM_PAINT handler you can use BitBlt for a fast copy to the Screen DC. This way you avoid the anoying flicker when working with complex drawings.

|
|
|
|
That's not always enough to get rif of the flicker. You also need to stop erasing of the background, if the window class has a background brush set.

How to manage Accelerator key when a modeless dialog os activated ?
My application use the F5 key as an accelerator defined at Mainframe level to open or close the modeless dialog.
Unfortunalty when the modeless dialog is activated and has the hand, key events are no more processed, nor accelerators. So F5 key has no effect.
Thank's in advance for your help;).

Highlight your classname and go to properties Tool window. There you can set Events, Overrides and Messages etc.

Hi
I am writing a WMI application to monitor the file system events in my system.i had converted the query given in http://www.microsoft.com/technet/scriptcenter/resources/qanda/apr05/hey0404.mspx" into a WQL in c++. But i am getting an error message Query execution failed. Can anyone help me in this regard.
Is it possible to monitor the entire system for file system changes using WMI ?

Dear Experts,
I need some information on dynamic updation of XML file.
Our application asks the user to insert a file by giving the user browsing option.
We want our XML file (which contains the information about the residing files) to be dynamically updated as soon user specifies the path of the inserted file.
The next task is to dynamically update the XML file once the user select the file to be deleted by clicking on the Application UI.
We have to develop the code in C++.
Kindly send across your suggestion, opinion and helpful codes.
Regards,
Mayank Srivastava

You're basically talking about using the XML DOM, I would have thought. If you're not doing this already, how do you read/write your XML files ?

Just do it like you do it with any other file - fopen(), fread(), fwrite(), fclose(). If that's vanilla C++ you want of course.

Hello
I suggest you considder to use a SAX parser. SAX has less memory (and CPU) overhead than DOM.
If you use MSXML, there are plenty of samples at MSDN.

Actually, no. You're telling him to do it in C. I would hope that most people using C++ would never use these functions.

Yeah, right. What's so bad about them anyway apart from being clumsy ?

That's about it, it's clumsy, it's ugly and C++ provides a good alternative that is rich in functionality that C file handles cannot offer.

Could anybody point me to a basic source of information on using struct in functions - passing as parameters and returning from functions.
I am confused regarding the difference in C an C++ syntax.
I am looking for using arrays of struct.
Thanks for your time

Passing arrays is the hard bit, a struct is just like a class, you can pass it in and you can pass it out. If I wanted to return an array of items, I'd probably take a std::vector by reference, and add them to that.

Structs are typically passed by pointer. In the case of struct arrays, it really depends on how you allocate the array. By incrementing a struct pointer, you actually increment the pointer to point to the next struct (the compiler increments it by the sizeof() the struct).
EX:
typedef struct _MyStruct
{
int iValue;
char caData[21];
} MyStruct;
MyStruct *StructFcn(MyStruct *spStruct, int iCount);
void PassStructToFcn()
{
MyStruct *spRetval = NULL;
MyStruct sStruct;
sStruct.iValue = 7;
strcpy(sStruct.caData,"Hello");
spRetval = StructFcn(&sStruct,1);
}
void PassStructArrayToFcn()
{
MyStruct *spRetval = NULL;
MyStruct sStruct[3];
sStruct[0].iValue = 2;
strcpy(sStruct[0].caData,"Hello");
sStruct[1].iValue = 3;
strcpy(sStruct[1].caData,"Hello");
sStruct[2].iValue = 7;
strcpy(sStruct[2].caData,"Hello");
spRetval = StructFcn(&sStruct[0],3);
}
MyStruct *StructFcn(MyStruct *spStruct, int iCount)
{
for (int iLup = 0; iLup < iCount)
{
if (spStruct->iValue == 7)
return spStruct;
spStruct++;
}
return NULL;
}
onwards and upwards...
