My company are using this library Solid FFmpeg C# .Net Wrapper . It's a quite good and powerful ffmpeg wrapper. Especially for beginners. You can try it and decide by yourselves.

Hi,
I have an interesting problem.
I have a tray utility program with various menu options that in turn bring up different dialog boxes. I want each dialog box to work as if they were modeless, but track them as if they were modal. I have solved this by making each box modal but have them on individual threads with a boolean to track if it is open or not.
Some code...
#region Configure MenuItem
private bool MyFormStarted = false;
private MyForm MyDlg;
private void MyDlgMenuItem_Click(object sender, EventArgs e)
{
if (MyFormStarted)
{
if (MyDlg.InvokeRequired)
{
MyDlg.BeginInvoke((ThreadStart)delegate()
{
});
}
else
{
}
}
else
{
MyFormStarted = true;
new Thread(new ThreadStart(delegate
{
MyDlg = new MyForm ();
MyDlg.ShowDialog();
MyDlg.Dispose();
MyFormStarted = false;
})).Start();
}
}
#endregion
I have a block of code similar to this for each dialog that the tray utility is to open. By doing it this way, I can allow the opening of multiple dialog boxes at the same time while ensuring that each dialog can only be opened once.
What the problem is though, I cannot work out how to put the selected dialog on top. I have rem'ed out the MyDlg.Show() because this does not seem to work. I have tried
MyDlg.BringToFront();
MyDlg.Focus();
As well, but while the form obtains the focus, I cannot get it to display on top. I think it might have something to do with the threads.
So I guess ultimately my question is this: Is there a way to bring one thread in front of the other as 'BringToFront' would do to to the form?
Obviously, I will have to use a private class variable to hold the thread instance, but then what should I do with it.
Regards,
David

Thanks Shameel,
That worked. I had to follow it immediately with a:
MyDlg.TopMost = false;
So it did not stay on top. But that was the answer I was looking for.
Thanks again,
David Bailey.

I'm working on a application which simulates a pdf reader. I have a issue with traversing the page. Following are the details.
there are two buttons called, "Previous View" and "Next View". These fulnctionality of these two buttons is I can navigate to the previously visited pages.
My requirement is as follows.
Lets say I visit page 1, followed by 10, followed by 15, followed by 12 and back to 10.
i.e, 1->10->15->12->10.
Suppose If I'm @ page 12. if I click on "Previous View", I should nagigate to page 15 and If I click "Next View" I should go to page 10.
My issue is, Suppose I'm @ the last visited page. that is page 10, after page 12. If I click I "Next View" it should not navigate, because it is the last visited page. But what happening is it is navigating to page 15. The reason for that is I'm checking only for the first occurenece of a element. which is @ 2nd position.
this happens only if there is multple occurenec of a element.
I need help in developing the logic.
any suggestion is appreciated.

Well, maintain your position / index in the array; don't start searching for the page "you know you are already on".
Based on your scenario, your "index" should be 4 (i.e. the last "10") and you know you can't move "next" because the "count" of the items in the array is not greater than index + 1 (using 0 based addressing).
Moving to a new page directly, you simply add that page number to the end of the array, and set the current index to that entry.
Moving "previous", decrement the index; until it reaches 0, at which point you know you're at the first page visited.

search CP articles about "history" or "undo/redo". There is at least one very good one I remember.

Hi
I am trying to insert a DataGridViewComboBoxColumn, the column is getting inserted but without values (options) in the combobox.
The Code is as under
<br />
DataGridViewComboBoxColumn column = new DataGridViewComboBoxColumn();<br />
column.HeaderText = "SELECT";<br />
column.Name = "ItemSelect";<br />
column.CellTemplate = new DataGridViewComboBoxCell();<br />
column.Items.AddRange("One", "Two", "Three");<br />
column.DropDownWidth = 160;<br />
column.Width = 90;<br />
column.MaxDropDownItems = 3;<br />
column.FlatStyle = FlatStyle.Flat;<br />
myDataViewGrid.Columns.Insert(0, column);<br />
When I run the code, in datagridview all cells except 1st are populated properly, in first cell I see only empty combobox.
Also, after showing the value, which event should I use to get the selected value of combobox?
Please guide
Thanks in advance

Yes you are missing something. You would be way better off posting your question here[^] since he more likely to see it there than here. And posting a question about a VB article in the C# forum is almost certainly not going to get you an answer.
Why is common sense not common?

My C# program is set to target the 2.0 version of the .NET Framework.
I used one of the overloads of WaitHandle.WaitAny that's only available in the 3.0 version of the framework, and it let me build the program and run it!
Is this supposed to occur?
The problem is that when I run the program on a machine that only has version 2.0 of the framework, the program crashes, of course.
But why did Visual Studio allow me to use an overload from the 3.0 version when it shouldn't have?
|

Actually 3.0 is a update to 2.0. It runs over 2.0. Thus if you build your project with a machine which have 3.0 installed, it will automatically take it as 3.0 (if not specified explicitly while creating project in VS 2008 IDE).
The project you built has taken 3.0 framework.Thus it requires it when running to a machine having 2.0 and crashes.
3.0 is not a new framework, but just an enhancement to 2.0.

Is there an API for the Win32 CreateProcess interface with all functionality available in C#/.NET?
I'm seeking for an example and would be very grateful for one.
|
|
|
|

You're either going to use the Process class in the System.Diagnostics namespace or you can P/Invoke the CreateProcess function yourself. Go to http://www.pinvoke.net[^] for details.

Have a try:
using system.diagnostics;
process.start("excel.exe");

Hi
i have treeview and it has some parantnode and chilenode;
i want when user checked(select) parantnode all of that chilnode's checked automatically;
what should i do?
|
|
|
|
|
If a parent node is clicked, you'll have to write code to enumerate all of its child nodes and check them.
|
|
|
|
|
I would implement an event handler for the AfterCheck event of the TreeView : in that event handler : if the checked Node has child Nodes : call a recursive function passing the TreeNodeCollection of the Node to the recursive function which will check all the child nodes, or do whatever else you want to do.
best, Bill
