In dataGeidView set property Modifiers to true and in form AddItem bind datagridview which is in form ViewItem.

Use delegates to cause events to happen between forms.

how can i use the delegates.tell me in detail or any example...
|

I like to give just the keywords. Anyone with any chance of ever becoming a programmer, should be able to type 'C# delegate' into google and find tons of articles to read.

Replace

with
where [group]

Loop in all items of Listbox and while looping get only selected items.
e.g.
StringBuilder sb = new StringBuilder();<br />
for (int i=0;i<=listBox1.Items.Count-1;i++)<br />
{<br />
if (listBox1.GetSelected(i) == true)<br />
{<br />
sb.Append(listBox1.Items[i].ToString());<br />
sb.Append(",");<br />
}<br />
}<br />
string values = sb.ToString();

i m getting error
Error 1 : The type or namespace name 'StringBuilder' could not be found (are you missing a using directive or an assembly reference?)
how to declare this name space??
|
|
|
|

Include using namespace System.Text on top of class,or use System.Text.StringBuilder sb = new System.Text.StringBuilder();

char *samplesBuffer
int offset = 20;

You can't. C# doesn't support that sort of pointer arithmetic. You'd have to pass in the starting index instead. The good news is, the array knows it's length, in C++ you'd still have to pass in a length so you knew how far you could go in it

Hello,
I have a project from the university to implement the fax protocol (in any language I want).
The idea is to write a software that will be able to receive a fax from a real fax machine. It can be done in any way I want - any language/environment , via modem or some other idea.
I know how the fax protocol works and I wrote a simple implementation already. The problem is actually running it.
I tried writing a C# program using SerialPort class and to access the modem's received data. The problem is that the modem does its own thing upon connecting and doesn't give me control over the received data.
I ran out of ideas at this point.
What else can I do?
Thank you very much.
