The ShowWindow function can minimize, maximize, or restore a window. It can also set the window's visibility and activation states.
MSDN link for ShowWindow[^]
Take a look at www.pinvoke.net[^] the pinvoke wiki

I tried using the ShowWindow but it just won't work, what I'm trying to do is put an application like notepad or paint or anything else inside windows forms
private void btnStart_Click(object sender, System.EventArgs e)
{
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.FileName = "notepad.exe";
processInfo.WindowStyle = ProcessWindowStyle.Hidden;
Process process = Process.Start(processInfo);
Process[] procs = Process.GetProcessesByName("notepad");
if (procs.Length != 0)
{
IntPtr hwnd = procs[0].MainWindowHandle;
CloseWindow(hwnd);
SetParent(hwnd, pbDisplay.Handle);
ShowWindow(hwnd, 5);
}
else
{
MessageBox.Show("Notepad is not running");
}
}
It seems there is some issue with the process focus or something like that, haven't found much info. about the topic, anyone has any idea?

What do you mean by "inside windows forms"?

I mean that I have a form in winforms that has a picture box in the code below called pbDisplay, I get the handler of the picture box and with SetParent() I put the notepad inside the picture box
I start notepad hidden so the user doesnt see when the notepad opens outside the application, but the problem is now that the notepad is inside how do i change the status from hidden to normal or maximized
In fact the application I want to put inside the picture box is called IPass, but I'm hoping that after being able to do it with notepad the change wont be that much problem
**************************
private void btnStart_Click(object sender, System.EventArgs e)
{
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.FileName = "notepad.exe";
processInfo.WindowStyle = ProcessWindowStyle.Hidden;
Process process = Process.Start(processInfo);
Process[] procs = Process.GetProcessesByName("notepad");
if (procs.Length != 0)
{
IntPtr hwnd = procs[0].MainWindowHandle;
CloseWindow(hwnd);
SetParent(hwnd, pbDisplay.Handle);
ShowWindow(hwnd, 5);
}
else
{
MessageBox.Show("Notepad is not running");
}
}

Well, what your doing is definitly non-standard. There is no documentation describing what your doing and what the side-effects are. ShowWindow works perfectly in all other instances.

Has anyone ever tried to code a piece of software to browse his bank(hsbc for instance) accounts, buy sell stock shares thru this software. This software is not meant to be only with ASP.NET, it can also be built using MFC or any other related libraries of .NET framework or previous Microsoft related libraries. I have got a similar piece of code in Java, however I would like to study its .NET version, what would it be like and what libraries of framework would be used, what methods be called to make a connection to the bank's server, browse accounts and buy and sell stock shares. I am trying to code a non-asp version of it for http://www.hsbc.com.tr/. Does anyone have any idea. I would later automatize my buying and selling thru some technical indicators..
Thank you for any opinions..

I was trying to implement:
Form_MouseEnter(object sender, System.EventArgs e)
{
if(!this.Focused)
this.Focus();
}
I have child controls that fill the entire form... so MouseEnter event never gets fired. I figured that MouseEnter would fire as soon as the mouse touched the form border, but that is not the case as it only gets fired when inside the border (and if you have child controls that fill the form background, then it will never get fired). It would be nice to have all child controls automatically inherit the parent's event handlers (without writting a function call: ChildControl_MouseEnter { Form_MouseEnter } for every child control).
It appears that every child control overrides the parent's event handlers (at least out-of-the-box microsoft controls... not neccessarily true for custom controls).
Is there an easy way to have child controls automatically call their parent event handlers without implementing the child's mouseEnter event?
Better yet, is there a way that you can have event handlers fire based on the Windows Form Border (which seems to be tied into the O.S, such as when you click the title bar of a form... the control gets focus)?

You could do this by manually setting the Region of the control. Search google for "non-rectangular forms" or similar for some examples of setting the region.

How would that solve the problem of firing events for the window frame? Sure you could draw only the client area then draw the borders yourself, but 1) what a pain in the arse, and 2) you could achieve that by simply setting Form.FormBorderStyle to FormBorderStyle.None.

To be honest, I didn't read through his entire post, I saw it about to fall off the board's main page without replies, so I posted.  I guess my thinking was that by setting the region of the form, you could have events be raised even if you were outside the client area.

Events are only fired for the client area. Setting the region to a small value changing the client area (and can mask the window frame). You can't really increase it, though. A window must be confined to the RECT defined for its window class.

Interesting, I'll have to try that out and see for myself.

Events are only fired for the client area and not the window frame. To receive messages for the window frame, you need to handle the appropriate WM_NC* window message by overriding WndProc.
Search for WM_NCMOUSEMOVE[^] in this forum for examples about how to implement this.
You should also read Consuming Unmanaged DLL Functions[^] and about the Windows Controls[^] - the Common Controls which most Windows Forms controls encapsulate to provide a consistent user interface.

I have a process I am starting up, but it doesn't seem to hid like I would have had it start.
Process someProcess = new Process();
someProcess.StartInfo.FileName = "C:\\someconsoleapp.exe";
someProcess.StartInfo.Arguments = "";
someProcess.StartInfo.CreateNoWindow = true;
For some reason this code didn't work. Is there some way that I can make the console app hidden from within the actual console app itself?
Cheers,
Jim

I think the following should solve your problem:
someProcess.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden

Thank you so much! That worked beautifully!

I am trying to filer rows from the database by passing the user input from the textbox to the rowfilter but not working. Here is the code.
DataViewManager myDVM = new DataViewManager(ds);
string filter;
filter = txtSearch.Text ;
myDVM.DataViewSettings["ExpungeName"].RowFilter = "LastName Like 'filter%' ";
However, if I do it directly without the textbox input, it works. Please help.
DataViewManager myDVM = new DataViewManager(ds);
myDVM.DataViewSettings["ExpungeName"].RowFilter = "LastName Like 'Jones%' ";

Your statement doesnt integrate the string in filter into your RowFilter. Change your statement to:
<br />
myDVM.DataViewSettings["ExpungeName"].RowFilter = "LastName Like '" + filter + "%' ";<br />

...
...
FileInfo file = new FileInfo("c:/somefile.txt");
file.Delete();
Hope this helps,
