Re: HEX to INT Steven Richardson15-Feb-02 2:48 Steven Richardson 15-Feb-02 2:48  sorry i am not sure how to implement this on to a decrypt button? when i press encrypt i get something like this: 68 65 72 65 73 20 77 68 61 74 20 68 61 70 70 65 6E 73 0D 0A and that says: heres what happens so i need the button to change it back from numbers to the text? Re: HEX to INT moliate15-Feb-02 3:14 moliate 15-Feb-02 3:14  Perhaps it is not the best solution for you. Anyway, what the function does is taking a string like |6|8|\0| and turn it into the number 104 decimal - the ascii code for 'h'. If you can access each line as a string, you can send it to the function and get back a char. The string must be null-terminated, though. /moliate Re: HEX to INT Rick York15-Feb-02 5:13 Rick York 15-Feb-02 5:13  Those are all ASCII character values displayed in hex. Try sprintf with a %c format specifier to get the text character. See the docs on sprintf for more details. Re: HEX to INT Steven Richardson15-Feb-02 6:19 Steven Richardson 15-Feb-02 6:19  right heres what i have now: Encrypt: AnsiString EditText = RichEdit1->Lines->Text; for (int i=1;i<=EditText.Length();i++) { Form1->Tmp = Form1->Tmp + IntToHex(EditText[i],2); } RichEdit1->Lines->Text = ""; RichEdit1->Lines->Text = Form1->Tmp; Form1->Tmp = ""; Decrypt: AnsiString DeCrypt = Form1->RichEdit1->Lines->Text; int i = 1; int l = 2; for ( ;i<decrypt.length() &&="" l<decrypt.length();i="i" +="" 2="" ,="" l="l" 2)="" { ="" form1-="">Tmp = DeCrypt[i]; Form1->Tmp = Form1->Tmp + DeCrypt[l]; Form1->RichEdit1->Lines->Append (Form1->Tmp); } so now: hello when encrypted = 68656C6C6F0D0A and on decrypt i get: 68 65 6C 6C 6F 0D 0A so tmp contains the temp string for each letter i now just need tmp to be converted? MFC Metafile to --> ATL ActiveX Braulio Dez15-Feb-02 0:38 Braulio Dez 15-Feb-02 0:38  Hi, I need to give as a param a metafile created with my MFC application to an ActiveX object that I´ve created with ATL ( my idea is to display that Metafile in the ActiveX Object). Sorry but I´m, a little bit novice in COM, what is the good way to do that ?, Thanks Braulio How to make a view in the main frame to have a flat look ? Armen Hakobyan15-Feb-02 0:05 Armen Hakobyan 15-Feb-02 0:05  How to make a view in the main frame to have a flat look, not sunken? Same with splitters. Playing with window styles does not do. If any one knows a tested solution, please reply. Thanks in advance. Re: How to make a view in the main frame to have a flat look ?

But when I compile with this option or MFC in a Static Library, I have the same executable file size. I notice that when I use Shared DLL option, it's linking statically too. I would appreciate your help. Thank you Vanessa a simply question about dlls Gérald Mercet14-Feb-02 23:41 Gérald Mercet 14-Feb-02 23:41  Hi, it's the first time i try to create a dll application which could be used from excel. So i try to do it by creating a MFC dynamically linked dll, where i put a simply code for a simply function: ///////////////////////////////////////////////////////////////////////////// // The one and only CEssai2App object CEssai2App theApp; extern "C" __declspec(dllexport) int Maximum(int a,int b) { AFX_MANAGE_STATE(AfxGetStaticModuleState()); int max; if(a Re: a simply question about dlls Joaquín M López Muñoz15-Feb-02 1:41 Joaquín M López Muñoz 15-Feb-02 1:41  I guess you forgot the __stdcall (aka WINAPI) specifier. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: a simply question about dlls Gérald Mercet15-Feb-02 1:58 Gérald Mercet 15-Feb-02 1:58  could you more explicit? because i'm a beginner in this kind of application... Re: a simply question about dlls Joaquín M López Muñoz15-Feb-02 2:04 Joaquín M López Muñoz 15-Feb-02 2:04  Of course. Define your function as follows: extern "C" __declspec(dllexport) int <font color=#ff0000>WINAPI</font> Maximum(int a,int b) If you're curious about that WINAPI thing, have a look at Nemanja Trifunovic's Calling Conventions Demystified Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: a simply question about dlls Gérald Mercet15-Feb-02 4:24 Gérald Mercet 15-Feb-02 4:24  I tried to do it, and it didn't work, so do you have any other suggestion, because i'm lost Re: a simply question about dlls Carlos Antollini15-Feb-02 4:53 Carlos Antollini 15-Feb-02 4:53  Try to add the .def file, in it you can define the function to export. Sometimes VB can't access to the function. How you are declaring the function un VB or vba?? Regards... Carlos Antollini.

Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: a simply question about dlls Gérald Mercet17-Feb-02 22:27 Gérald Mercet 17-Feb-02 22:27  you were right for the typo, i change it and it brought nothing into the way of no working of my application... have you any other idea because i don't succeed in solving my pb?
