I have a Char which containes a number, example 32. How do I convert the char to INT? char cTest[100]="32"; int iTest; now I want to convert the cTest to iTest so it's a integer instead of a char. Any function which can do this? thanks for any info. Re: Char to INT? Alvaro Mendez11-Dec-02 9:12 Alvaro Mendez 11-Dec-02 9:12  atoi. int iTest = atoi(cTest); Regards, Alvaro Well done is better than well said. -- Benjamin Franklin (I actually prefer medium-well.) Re: Char to INT? Nitron11-Dec-02 13:23 Nitron 11-Dec-02 13:23  i'll second that. also, if you need a double, atof: double data = atof(szData); - Nitron "Those that say a task is impossible shouldn't interrupt the ones who are doing it." - Chinese Proverb Re: Char to INT? Greven11-Dec-02 9:21 Greven 11-Dec-02 9:21  I think the easiest way would be to simply cast it... iTest = (int)cTest[i]; Wouldn't that work? Programming in binary is as easy as 01 10 11. Re: Char to INT? Alvaro Mendez11-Dec-02 9:29 Alvaro Mendez 11-Dec-02 9:29  Nope, it wouldn't work. Only the first character would be converted, and to it's ASCII value -- which is not what he needs.

Didn't see the quote around 32... Thought he had an array of char's, not a string. Programming in binary is as easy as 01 10 11. Re: Char to INT?

Thanks Catching OnSysCommand in own class BtL2711-Dec-02 8:44 BtL27 11-Dec-02 8:44  Hi, i think this problem may be easy to answer for you. I have created my own class: -header-file: class CTrayIcon : public CWnd { public: CTrayIcon(); // Konstruktor virtual ~CTrayIcon(); // Dekonstruktor int AddTrayIcon(HICON pIcon,int iMenu); protected: // Overrides // ClassWizard generated virtual function overrides //{{AFX_VIRTUAL(CTrayIcon) //}}AFX_VIRTUAL protected: //{{AFX_MSG(CTrayIcon) afx_msg void OnSysCommand(UINT nID, LPARAM lParam); //}}AFX_MSG DECLARE_MESSAGE_MAP() }; The Class-Wizard automatically adds the function OnSysCommand to the header and of course to the cpp. Now, i do not know, what i must do, that all messages of the dlg-window(main-dialog-window), especially WM_SYSCOMMAND, can catch in my class ?

Type Libraries and MFC Question Nick Parker11-Dec-02 8:40 Nick Parker 11-Dec-02 8:40  I have written a .NET assembly that I want to use in MFC 6.0. According to an MSDN article[^], I need to use the Regasm.exe to make the necessary entries in the registry. I have gone ahead and done this using the following command to create a type library as well: regasm mcpp.dll /tlb:mcpp.tlb From what I understood, I then needed to reference the type library that is created one of two ways: #import "mcpp.tlb" raw_interface_only or #import "mscorlib.tlb" #import "mcpp.tlb" I have done this however as soon as I try to compile following this it throws a slew of error within either mcpp.tlb or mscorlib.tlb, depending on which item I try (as I have tried both methods). Does anyone have any experience doing anything of this nature. Thanks Nick Parker Not everything that can be counted counts, and not everything that counts can be counted. - Albert Einstein Copying CString to char* Like2Byte11-Dec-02 8:32 Like2Byte 11-Dec-02 8:32  Hi, I need to output some CString data after I've copied it to a char array (ie: char ptrSomeCharArray[33]). I can't seem to get the data extracted from the CString object. I've tried: CString m_sFullname("Like2Byte"), m_sAccount("12345678"), m_sRoom("222"); char SomeCharArray[33]; sprintf( SomeCharArray + strlen(SomeCharArray), "%s", m_sAccount); sprintf( SomeCharArray + strlen(SomeCharArray), "%s", m_sRoom); sprintf( SomeCharArray + strlen(SomeCharArray), "%s", m_sFullname); While this compiles without error, inserting it into a MessageBox function displays garbage. Even wrapping the var in TEXT() doesn't work. I've also tried casting using LPCTSTR, LPTSTR and (const char*). None work correctly. Anyone help out? Re: Copying CString to char* User 665811-Dec-02 8:43 User 6658 11-Dec-02 8:43  Have you tried e.g. sprintf( SomeCharArray + strlen(SomeCharArray), "%s", m_sAccount.GetBuffer(0)); ? But err, what does the sprintf do? Do you want to append the CString to SomeCharArray? You should use strcat instead regards modified 12-Sep-18 21:01pm. Re: Copying CString to char* Like2Byte11-Dec-02 8:49 Like2Byte 11-Dec-02 8:49  Well, I tried m_sAccount.Mid(0) but that gave me the same results are m_sAccount. Let me try your suggestion. (The 'In a nut-shell' explination)sprintf basically copies whatever kind of data to end of another string converting it to a string when it's all done. say, SomeCharArray contains "HelloWorld" and someIntValue = 32768. Therefore, sprintf(SomeCharArray + strlen(SomeCharArray), "%i", someIntValue); copies 32768 to the end of SomeCharArray; thus, leaving, "HelloWorld32768". (BRB) Re: Copying CString to char* Michael Dunn11-Dec-02 8:49 Michael Dunn 11-Dec-02 8:49  Any time you use a string object (CString or any other string wrapper class) with the printf family of functions, you need to cast the object to a pointer type, so that only the pointer is put on the stack. sprintf( SomeCharArray + strlen(SomeCharArray), "%s", (LPCTSTR) m_sAccount); But as Gregor said, the real bug in your code is how you construct the string in the first place. Just use one sprintf() call. --Mike-- Friday's GoogleFight results: Britney Spears 2,190,000 - Erica Weichers 23 1ClickPicGrabber - Grab & organize pictures from your favorite web pages, with 1 click!

(BRB) Re: Copying CString to char* Alvaro Mendez11-Dec-02 8:56 Alvaro Mendez 11-Dec-02 8:56  You can use strcpy, like this: strcpy(SomeCharArray, m_sAccount + m_sRoom + m_sFullname); However, you need to be careful that the length of the 3 variables does not surpass the size of SomeCharArray - 1.

Re: Copying CString to char* carrie11-Dec-02 10:39 carrie 11-Dec-02 10:39  yeah, thats the method I would use. Nice and easy Re: Copying CString to char* Gary R. Wheeler11-Dec-02 14:55 Gary R. Wheeler 11-Dec-02 14:55  You need to initialize SomeCharArray to an empty string, either via SomeCharArray[0] = '\0'; or strcpy(SomeCharArray,""); otherwise, you're concatenating at an arbitrary location in the string. Another way to do this would be sprintf("%s%s%s",m_sAccount,m_sRoom,m_sFullname); Software Zen: delete this; Re: Copying CString to char* Shay Harel11-Dec-02 17:36 Shay Harel 11-Dec-02 17:36  Try this : CString str="Hello"; char *pStr=str.GetBuffer(0); Thsi should return a pointer of type char representing the string content, always works for me.

Handling Checkbox changes in CListCtrl DRHuff11-Dec-02 7:13 DRHuff 11-Dec-02 7:13  I have a CListCtrl in report mode with checkboxes. With several lines of data I can check/uncheck the check boxes without shifting the selection or getting any update other than an ItemChanged update. I need the checkbox change to be reflected back and set the current selection to the item changed. How do I do this? I have tried to handle it in the OnItemChanged but I get some really bizarre behaviour. Dave Huff Igor would you give me a hand with the bags? Certainly - you take the blonde and I'll take the one in the turban! Re: Handling Checkbox changes in CListCtrl Joan M11-Dec-02 7:38 Joan M 11-Dec-02 7:38  take a look at this link... http://www.codeproject.com/listctrl/listctrldemo.asp[^] hope this helps...
