delete[] the old memoryadress before reallocating.
Hold the new address in another variable.
Use a string class (e.g. std::string or CString), which handles the memory for you.

You shoudln't mix new and realloc.

Yes, you are right. I was thinking in malloc context.

Use std::string instead of char arrays.

CString is much better optimized in this case!

Genrally when file is open in Exclusive mode, it doesn't allow other process to even read from it

I'm using the date control on a dialog. When the dialog is displayed I need to set the day field of this control to be selected. Can anyone tell me how to do this?
thanks,
Andy

Are we talking about a CDateTimeCtrl here?
Normaly, you call SetTime() on a control-variable of type CDateTimeCtrl you added to your dialog.
This would require the time you want to set in a CTime or COleDateTime class or a SYSTEMTIME structure.
Another, more complicated, way would be to send the control a DTM_SETSYSTEMTIME message.

Use GetMonthCalCtrl to get CMonthCalCtrl from a CDateTimeCtrl. Use SetCurSel to select a date.
Sample from MSDN:
CDateTimeCtrl* pCtrl = (CDateTimeCtrl*) GetDlgItem(IDC_DATETIMEPICKER1);
CMonthCalCtrl* pMoCalCtrl = pCtrl->GetMonthCalCtrl();
CTime dt2(1998, 3, 15, 0, 0, 0);
pMoCalCtrl->SetCurSel(dt2);

ok, I think I may not have explained it clearly enough, what I need is for the day field of the control to be selected (i.e. if the user types then the day changes). I'm using a Date Time control which is liniked to a CDateTimeCtrl object.
cheers,

I have a little application called updater.exe. This updater gets called by the other application called someapp.exe. Updater receives three arguments
1. calling application (full path of someapp.exe)
2. location of the installer file
3. installing destination folder
So when someapp.exe calls updater.exe it immediately exits (it will get overwritten). Because this exiting process isn't instant, updater should check if it's still "alive". How can I do this? Can I get some handle from 1st argument and check if application is still running?
Best regards,
Rostfrei

You could use a kernel object, as describes by Christian Graus here[^].

Have the calling process pass a HANDLE to itself to the callee. Make sure this HANDLE is inheritable and then when you call CreateProcess to create the callee ensure the bInheritHandles argument is set to TRUE. The callee can then call WaitForSingleObject passing in this HANDLE to wait until the caller has exited.

I have a char* that holds a numeric value of for example: 172,500 and I want to multiply this by another number and write the contents back to a new char*. Could someone give some example code on how to easily achieve this?
|
|
|
|
|
You can use atoi and itoa functions to achieve this.
atoi - converts string to int.
itoa - converts int to string.

Actually is there a comma (,) ?
