Re: Strings in VC Form buttons

[adelle]

Experienced Boreland C programmer moving to VC - it's about time!

So I dragged over a data structure from a DOS application, included it in the *c++ file and the it compiles.

Now I want to use that structure to place the text in from buttons.

where:

this->button2->Text = L"button2";

I am modifying as follows:

this->button2->Text = src_lev[1].src_name1;

and I get an error!

structure file snippit. This is a proven good Boreland C file.

#define XPF 9999

struct src_list {

char *src_name1;
char *src_name2;
int src_num[11];

} src_lev[] ={

/* src top row bot row PAN HDa HDb SD REF LTC CNTL A12 A34 A56 A78 */
/* 0 */ "", "", XPF, XPF, XPF, XPF, XPF, XPF, XPF, XPF, XPF, XPF, XPF,
/* 1 */ "ResMac-1", "", 1, 5102, 5103, XPF, 193, XPF, XPF, 5104, 5106, 5108, 5110,
/* 2 */ "ResMac-2", "", 2, 5115, 5116, XPF, 194, XPF, XPF, 5117, 5119, 5121, 5123,
rest of structure not shown

Well, I guess you are not the first person getting this error message: https://www.google.de/search?q=C2664...hrome&ie=UTF-8

Thank You. That advice fix it.

this->button1->Text = gcnew String(src_lev[1].src_name1);
