SetWindowText Error

[VinayCool]

Hi, I have long value i am want to show in the dlg i used below code but its giveing error can any one help me with this.. long n; n=INDX.total_words; status->m_TOTAL_WORDS.SetWindowText(n); --------------- Error --------------- error C2664: 'SetWindowTextA' : cannot convert parameter 1 from 'long' to 'const char *' Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast ---------------------------------------- Regards, Parichay.

The function SetWindowText expect a char array, not a long. So use sprintf to convert this value into a char array:

char szBuff[50];
sprintf(szBuff,"%l",n);
status->m_TOTAL_WORDS.SetWindowText(szBuff);

Hi WhiteSky, Thanks a lot its working ......:) TCHAR buffer[50]; long n=INDX.total_words; _ltoa(n,buffer,10); status->m_TOTAL_WORDS.SetWindowText(buffer);

Hi WhiteSky, Can u please also tell me how to change it int to char ?? TCHAR buffer1[50]; int f=INDX.getTotalFiles(); _ltoa(f,buffer,10); status->m_TOTAL_FILES.SetWindowText(buffer1);

[Hamid Taebi]

very simple _ltoa(f,buffer,10); to itoa(f,buffer,10);_**

_ltoa - Convert a long integer to a string. _itoa - Convert an integer to a string Knock out 'T' from CAN'T , You 'CAN' if you think you 'CAN' :cool:

[VinayCool]

Yes its working thanks a lot.

Can u please also tell me how to change it int to char ?? TCHAR buffer1[50]; int f=INDX.getTotalFiles(); _ltoa(f,buffer,10); status->m_TOTAL_FILES.SetWindowText(buffer1); Oops, I misunderstood his question. I thought he was asking about the line that does the conversion.

pleast look at my reply to whitesky. And Btw, you can still use ltoa for converting ints to chars. int is not something totally different from long. but Only the size ;)

Due to the differences in size of long and int C++ provides the seperate functions :) Knock out 'T' from CAN'T , You 'CAN' if you think you 'CAN' :cool:
