It's very difficult to make all of them...
The first option is not possible.
And the second one, is possible using a simple trick, only put the button, over the grid, in the point that you want. You can get the cordinated of a cell, and with that you can put the button in the correct place, usin SetWindowPlacement...

i have used INTtoHEX to convert some text to HEX but now I need to convert it back to read able text any cues?

AnsiString EditText = RichEdit1->Lines->Text;
for (int i=1;i<=EditText.Length();i++) {
RichEdit2->Lines->Text = RichEdit2->Lines->Text + IntToHex(EditText[i],2);
}
RichEdit1->Lines->Text = "";
RichEdit1->Lines->Text = RichEdit2->Lines->Text;
RichEdit2->Lines->Text = "";

Very crude, but i think this should work (send 2 chars at a time in your case)

int Hex2Int(char* hex)
{if (!*hex) return 0;

 int tmp = 0; 
 if (*hex >= '0' && *hex <= '9')
	 tmp = *hex - '0';
 else if (*hex >= 'A' && *hex <= 'F')
	 tmp = *hex - 'A' + 10;
 else if (*hex >= 'a' && *hex <= 'f')
	 tmp = *hex - 'a' + 10;

 return (tmp << (4*(strlen(hex)-1))) + Hex2Int(hex+sizeof(char));
}

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?

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.

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.

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?

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.

WS_EX_CLIENTEDGE gives the effect of the suken edge

Remove this bit from windows styles and you should be good.

Compiling MFC in a shared DLL

15-Feb-02 0:08

I'm working with eMbedded Visual C++ 3.0 and I'm having the following problem: I need to compile a project for HPC2000 device / Win32 (WCE ARM) Debug CPU using MFC in a Shared DLL. 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

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());

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

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??

After the definition in VC++ i put the following code in vba:
Public Declare Function Maximun Lib "D:\essai2\Debug\essai2.dll"(byval a as integer,byval b as integer) as integer

I have put it into a simple module, without anything else.

So, if you need of information on the code in "C", you could look at my first post.

thanks
