Hi All,
I am working on a tabbed application for my current project.
In the process of development i have see that my application behaves differently if i minimize and maximize the application using the minimize/maximize application button of the window and if i minimize/maximize it by clicking the application icon on the task bar.
what happens:
In the tabbed dialog d1 for a special case i am overlaying another dialog d2 so that i can see d2 only.
if i minimize the application using the minimize button and again maximize using the button, i can see the d2 dialog.
if i click on the application icon on taskbar to minimize and again maximize, d2 dissapers and d1 shows up.
I will appreciate if any one have inputs on this issue.

I hope you are calling SetActivePage( page index) and your code may need to remember which is current active page

Hi guys,
I'm creating a multi-threaded application using _beginthreadex() and _endthreadex(). If my thread executes correctly I call _endthreadex( 0 ) but if it doesn't I call _endthreadex( <some error code> ). How can I capture the thread's exit code in the main thread?
Thanks.

Just returning would be the best way to exit a thread.

Hi Rajesh,
I know that returning from a thread will call _endthreadex() but everything I have read says that "terminating a thread with a call to endthread or _endthreadex helps to ensure proper recovery of resources allocated for the thread". Is it safe to assume that returning will accomplish this?
Thanks,
Paul

Hi Paul,
masnu wrote: but everything I have read says that
The documentation is confusing (I presume you read the documentation? If there's some other source which recommends _endthreadex instead of just returning the control, please ignore it. It's wrong). The documentation could have better been:
"Do not call _endthread() or ExitThread() or TerminateThread(), etc., on a thread that was created by a call to _beginthreadex(). That will lead to resource leak. If you have to explicitly "end" a thread that was created by _beginthreadex(), then you should only call _endthreadex(). But just returning from the function is a better alternative." (similarly, _endthread and _beginthread is a pair)
It's been explained very elaborately on the book Windows via C/C++ (and probably in a couple of other books too). I remember Dr. Joseph Newcomer had written on this too, which I'm lazy to search for now.
masnu wrote: Is it safe to assume that returning will accomplish this?
Yes! The resource cleanup will happen perfectly if you simply return the control. To conclude, there's simply no reason to call _endthreadex (or any of their akin functions that explicitly "ends" a thread) from your code. Returning the control is the best thing to do! Let me know if you need more information.

OK, I just searched Dr. Joseph's article and it's here: http://www.flounder.com/badprogram.htm#AfxExitThread[^] (He's a man that has earned a lot of respect in the community, and he says "Doing this will result in erroneous programs").
Now it's 12.59 AM here and I better hit the bed or I'll wake up late. Good night (probably good day) to you!

I want to create a custom build configuration that creates an executable that is statically linked to all the run-time libraries. That way I do not need to worry about making sure all the necessary dll's are on the target machine. How do I do that in VS?
Thanks

Have you looked into project settings? In VS 2008, its' under Configuration properties -> General.

I got this error few days back (because of code base is complied from mapped network drive)
Once network was OK, Rebuilt and done.

No prob, I just thought you might have not.

This was just the first hit that I got and I thought it might help.

Hi to All,
I have 4 rows of data has to be saved in a binary file system . I haven't use it before, Can anyone please help me with this
EG:
struct A
{
int a1;
int a2;
}
struct B
{
int b1;
int b2;
}
struct C
{
int c1;
int c2;
}
How do I write and read this values from the file system??
-----------------------------
I am a beginner

You may simply store the structs as row, binary data. For instance (error checking left to the reader):
struct A
{
int a1;
int a2;
};
A a;
FILE * fp = fopen("data.raw", "wb");
fwrite(&a, sizeof(a), 1, fp);
fclose(fp);
For an object oriented approach see Object Serialization [^](for instance MFC framework supports it).

thanks for your reply.
But my problem is I have more then 2 structure and I need to search or write at runtime.

You may do a step toward serialization, storing type info just before actual data, for instance:
enum SER_TYPES
{
eTypeI,
eTypeD,
};
struct I
{
int i1, i2;
};
struct D
{
double d1, d2, d3;
};
void store(FILE *fp, I * pi)
{
int t = eTypeI;
fwrite( &t, sizeof(int), 1, fp);
fwrite( pi, sizeof(*pi), fp);
}
void store(FILE *fp, D * pd)
{
int t = eTypeD;
fwrite( &t, sizeof(int), 1, fp);
fwrite( pd, sizeof(*pd), fp);
}
int main()
{
FILE * fp = fopen("data.raw", "wb");
I i,j;
D d,f;
store(fp,i);
store(fp,d);
store(fp,j);
}
On reading, you've to first read the type of the stored data and then, according to the type, read the actual data.

thanks ,
that's the exact one i was looking for...In fact I dont have knowledge on serialization, But i have also reached t that point..Now I am having problem on reading...
just for ur information.....my incomplete code is given below
I have used class instead of struct
class tableSructureUnknown
{
};
class tableSructure1: public tableSructureUnknown
{
public:
int x;
int y;
};
class tableSructure2: public tableSructureUnknown
{
public:
int x2;
int y2;
};
class listTable
{
public:
int id;
int size;
char tName[20];
};
listTable ArrTableInfo[]=
{
{TFX_TABLE1,sizeof(tableSructure1), "first"},
{TFX_TABLE2,sizeof(tableSructure2),"Second"},
{TFX_UNKNOWN,0,"Unknown"}
};
FILE *ptr_myfile;
int writeToFileTable(int tableId,tableSructureUnknown *lpbaseTableClass)
{
ptr_myfile=fopen("test.bin","w");
if (!ptr_myfile)
{
printf("Unable to open file!");
return 1;
}
for(int i = 0; (ArrTableInfo[i].id != TFX_UNKNOWN) || (ArrTableInfo[i].id != tableId) ;i++)
{
fwrite(&ArrTableInfo[i], sizeof(listTable), 1, ptr_myfile);
ptr_myfile=fopen("test.bin","w");
if (!ptr_myfile)
{
printf("Unable to open file!");
return 0;
}
fwrite(&lpbaseTableClass, ArrTableInfo[i].size , 1, ptr_myfile);
break;
}
fclose(ptr_myfile);
return 1;
}
tableSructureUnknown* ReadFromFileTable(int tableId)
{
for(int i = 0; (ArrTableInfo[i].id != TFX_UNKNOWN) || (ArrTableInfo[i].id != tableId) ;i++)
{
}
tableSructureUnknown* temp = NULL;
return temp;
}
int main(int argc, char* argv[])
{
tableSructure1 Mytable1;
Mytable1.x = 1;
Mytable1.y = 11;
tableSructureUnknown *lpbaseTableClass = &Mytable1;
writeToFileTable(TFX_TABLE1,lpbaseTableClass);
tableSructure2 Mytable2;
Mytable2.x2 = 2;
Mytable2.y2 = 22;
lpbaseTableClass = &Mytable2;

I have 2 classes.
Class A:
void CDbModReactor::objectModified(const AcDbDatabase* pDb,
const AcDbObject* pDbObj)
{
AcAxDocLock docLock(pDbObj->ownerId(), AcAxDocLock::kNormal);
if(docLock.lockStatus() != Acad::eOk)
return;
else
gpDlg->OnCopy2Excell("modified", pDbObj);
}
Class B:
void CSampDialog::function1()
{
FILE * pFile;
pFile = fopen ("C:myfile.csv","a");
if (pFile!=NULL)
{
CString x2 = Cent_X+","+Cent_Y+"\n";
fwrite(x2, x2.GetLength(), 1, pFile);
fclose (pFile);
}
}
Now i have to call the function void CDbModReactor::objectModified(const AcDbDatabase* pDb, const AcDbObject* pDbObj) from void CSampDialog::function1()
How can i call...
Please help me...
