ok well i'm having issues sending a char array to a listbox. To do a little explanation on the code itself... The point of this part is to take a hexidecimal string and convert it to a alphabetical string (this part works and has been tested in a console application). I then have a vShowText function that i used to add items into my listbox. It has worked thus far and i have even added char arrays to the listbox using it. In this particular case i can't seem to make the char array show up into the listbox, it just inserts a line of D like characters. This is sorta difficult to explain so i hope i'm doing a good enough job of it. I will post code to help explain more below.
here is my vShowText function that is being used to insert text into the listbox.
void vShowText(HWND hChildHandle, char *szText) { int Line; // add string to the listbox SendMessage(hChildHandle,LB_ADDSTRING,0,(LPARAM)szText); // determine number of items in listbox Line = SendMessage(hChildHandle,LB_GETCOUNT,0,0); // flag last item as the selected item, to scroll listbox down SendMessage(hChildHandle,LB_SETCURSEL,Line-1,0); // unflag all items to eliminate negative highlite SendMessage(hChildHandle,LB_SETCURSEL,-1,0); }below is where my problem is. This is the actual code to change the hex string into a alphabetical one. When the loop is done going through the hex string, ptrBuffer is reset to point to the first element in the char buffer[100] array. Then vShowText is called to display the contents of the buffer array into the listbox. I have also tried to just do vShowText(hlistbox, buffer). Both of these methods does the same thing and inserts a line of D like characters into the listbox... so it looks something like this DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD. Only they aren't actual D's.
also i am able to just make a char array and then later call vShowText with the array as a parameter and it displays in the listbox fine. Example is below.
//create a char array
char myArray[100] = "Hello World!";//later in the program
vShowText(hlistbox, myArray);
the actual code snipplet:case MENU_FILE_TRANS: { char *ptrBuffer = &buffer[0]; for (int i = 0; i < RecvBytes; i+=2) { int firstvalue = RecvData[i] - '0'; int secondvalue; //if RecvData[i+1] is a letter convert it to integer, otherwise use it. switch(RecvData[i+1]) { case 'A': { secondvalue = 10; }break; case 'B': { secondvalue = 11; }break; case 'C': { secondvalue = 12; }break; case 'D': { secondvalue = 13; }break; case 'E': { secondvalue = 14; }break; case 'F': { secondvalue = 15; }break; default: secondvalue = RecvData[i+1] - '0'; break; } //convert the two values into decimal form newval = 16 * firstvalue + secondvalue; //change newval into a character *ptrBuffer = char(newval); //SendMessage(hlistbox,LB_ADDSTRING,0,(LPARAM)ptrBuffer); ptrBuffer++; //vShowText(hlistbox, ptrBuffer); } ptrBuffer = &buffer[0]; vShowText(hlistbox, ptrBuffer); }break;
I need some help man I can't figure this out. I am using code blocks with wxwidgets and I cant figure out how to CASE and SWITCH. Here is my code. All I have is a list box with some items in it and a button. I just want to be able to select an item and then press a button and have it do something like launch internet explorer or anything where each item will do something different. If I can get it to work I can figure it out from there. Thanks in advance for any help on this.
void ListBoxFrame::OnButton3Click(wxCommandEvent& event)
{
for (int i = 0; i < ListBox1.IsSelected.Count; i++)
{
switch (ListBox1.IsSelected[i].ToString())
{
case "Foobar":
wxLogMessage(_T("Listbox item foobar selected"));
break;
case "Bazquirk":
wxLogMessage(_T("Listbox item Bazquirk selected"));
break;
case "Widgets":
wxLogMessage(_T("Listbox item Widgets selected"));
break;
case "Gadgets":
wxLogMessage(_T("Listbox item Gadgets selected"));
break;
}
}
}
