I hadn't come accross that one Pete Thumbs Up | :thumbsup:

It doesn't help with this problem as the size (in bytes) of the uint array is held in the lower 24 bits of the uint that is the previous field. Whoever came up with that idea wants shooting!

They could have had the upper 8 bits of the other field as a separate byte parameter for the flags it relates to, and kept a field purely for the size of the array... it would have used just one extra byte of memory per struct when each struct can be thousands of bytes long already so not much difference Mad | :mad:

I try to do this:

void tabControl1_GotFocus(object sender, EventArgs e)
        {

            foreach (TabPage item in tabControl1.TabPages)
            {
                if (item.Focus())
                {
                    for (int i = 0; i < listBoxUsers.ListBoxControl.Items.Count; i++)
                    {
                        if (item.Text==listBoxUsers.ListBoxControl.Items[i].ToString())
                        {
                            listBoxUsers.ListBoxControl.SelectedItem = item.Text;
                        }
                    }
                }
            }

Hi,

IMO you may have to put such code inside a tabPage_GotFocus() handler for each of the tab pages.
Not sure the tabControl gets a GotFocus event when switching tab pages.

Send input to CMD from WINFORM

Create one listbox control that is shown on all pages. Simple and each page will reflect the same ListBox list and selected item.

Hi.

I have a winform that creates a process(cmd) and redirects its inputstream and outputstream to streamwriter and streamreader.

im able to write a command to that process(dir for example) and get the output and display it on textbox.
however, it seems that after i write to the inputstream i have to close it , only if i close the stream the command that ive sended is executed.

i want to be able to write more command to that stream and keep it open.

using the "flush" method on the streamwriter dosent seems to work.

how can i accomplish that task?

Does your command end with CR+LF?
It's just a guess but I think you need to send the equivalent of pressing Enter at a command prompt (i.e. in Cmd window).

Your app has a lot of problems with the console because console window doesn't belong to the caller process.If you want be able to read or write to console from Win forms in the same way like console application you should call AllocConsole or AttachConsole native functions to create or assign console window that belong to your windows forms app,not just to external process.To close current process console window you should call FreeConsole function.See some sample code here.

Getting type?

So i posted a question the other day about dynamically loading dll components. And it works great if I know the type like this(whatever.whatever):

Assembly asm = Assembly.LoadFrom(openFileDialog1.FileName);
Type myType = asm.GetType("whatever.whatever);
UserControl uc = (UserControl)Activator.CreateInstance(myType);
uc.Name = "uc";
this.Controls.Add(uc);

But now how would I do this without knowing the type before?

Thanks Smile | :)

Why would you be trying to add a control of a type that is unknown to you? In other words, if you don't know what "whatever.whatever" control exists in the assembly, why would you expect it to be there?

urgent anyone can save me....
