So which part are you having trouble with: 1) retrieving data from SQL, or 2) loading an image from disk?

CImage[^] (if you're using VS2003 or later) or CxImage[^] will load image files for you.

Hi Harish,
You could use strcat function provided in string.h to concatenate 2 strings. e.g strcat(str1,str2) concatenates str2 with str1.

Which kind of string ? C style strings ? Then use strcat. std::string ? Then use the + operator.

Use std::string or CString and then you can do it like this:

std::string a = "Hello ";
std::string b = "World";

std::string c = a + b;

CString a = "Hello ";
CString b = "World";

CString c = a + b;

Otherwise, if you just use C strings, you have to do stuff like this:

char a[10];
char b[10];
char c[20];
strcpy(a, "Hello ");
strcpy(b, "World");
strcpy(c, b);
strcat(c, a);

Track number of compiles done on a solution

I think you must post your problem in C# section. This board is for C++ related queries...

Hi All,
Is there any automated way in Visual C++ 2008 to count the number of times the solution gets compiled??

Why ? does it serve any purpose ?

no way that I know of, but you could do a "post-event" script that increment a value and put it in a file somewhere.

Actually i want to include the number of compiles done on project's solution in my application's version number. e.g. if solution has been compiled 2315 times then version number could be made as v1.0.2315

What commands does post event script accept?? C++, DOS or any other?? Could you plz specify how to do that???

Thanks for the reply. Smile | :)

Actually i am developing a console application in VC++. Earlier I thought of counting number of builds in some way and then adding the version information in readme file. After reading the suggested articles, I tried to integrate version information within application itself but the solution for those articles are for MFC applications i guess, since they are not working out in my console application. Confused | :confused:

Can you please tell me a way of integrating version information in console application. I have tried adding "Version" resource in "Resource Files" but I am not able to link it to console application. Also, the addin utility at [^] suggested by Mr. CPallini gives errror that VERSIONINFO Block was not found in .rc file. Kindly suggest me a way to integrate VERSIONINFO block in console application. And since i have posted this question 18 hrs back, i think slight modification might bring this thread under some attention otherwise i have to start a new discussion about this topic. Smile | :)

CcheckBoxList issue

Hi,

im using CCheckBoxList..and im poulating the checkboxlist based on an ini file...and in a loop im trying to check all the checkboxes using Setcheck method but one of checkbox is not checked when i see the output...ie when i debugged thru the loop in which im setting checkboxes im able to see every checkbox is checked but when it comes out of the loop one of the checkbox is not checked....i think it is rearranging checkboxes based on alphabetical order but i need it"s to be checked...

the below is the code...is present in oninitDialog..

CCheckListBox mchk;

mchk.ResetContent();
mchk.SetCheckStyle( BS_AUTOCHECKBOX );
mchk.AddString("All");
mchk.SetCheck( 0, 1 );

CString csage;
///im retrieving section keys of ini file into this vector...
std::vector Key;
///im retrieving values of keys into this vector...
std::vector Values;

for(int i=0;i<key.size();i++)>
{
csage=Values[i];
mchk.AddString(csage);
mchk.SetCheck( i+1, 1 );

}

the problem is i need to have "All" always as the first checkbox and some of the checkboxes are not getting checked...may be they are getting sorted but i need them to be checked ......
ie if i have a value "adidas" that is assigend to first checkbox which is not desired as always "All" should be the first checkbox..

CPallini13-Mar-09 3:43

Change

mchk.AddString(csage);
mchk.SetCheck( i+1, 1 );

int index = mchk.AddString(csage);
if (index != LB_ERR && index != LB_ERRSPACE)
{
  mchk.SetCheck( index, 1 );
}

If I understand properly your answer, you have to remove the LBS_SORT style in your list.
