How are you planning to display the graphic? Through a standard PictureBox control? Or are you going to draw it yourself?

Either case, you need to track the current position of the graphic using a variable and update the position in the button click.

It is actually am Image, so I guess a picture box control.

Then it becomes fairly simple. Just change the Top/Left properties of the PictureBoxControl and you're done.

Combobox problem

Boggy21-Oct-05 11:02

Hi,

My C# / Winform program talks to a COM (OLe Aotomation) server. I need
to pass the handlw of a combobox to the COM server and the server will
populate the combobox by sending CB_ADDSTRING message. The result is: the
combobox got populated but when I dropdowm (the combobox is DROOPDOWNLIST
style) I got very narrow dropdown part with a tiny scroll bar, and if I
select an item I got a System.ArgumentOutOfRangeException. In code just
after the server populated the combobox I can see that MyCombobox.Items.Count is 0. We know in C# .NET code we add string to combobox this way: MyCombobox.Items.Add("abc"). It seems if we use the
CB_ADDSTRING to add strings to a .NET combobox the Items is empty.

Any one got the similar problem?
Thanks in advance for any help.

Windows Controls are not thread safe.Any
attemp to play with them in external code may result to undesirable results such as yours.

If you can return that string (for example via an event in that activex) to your code this
whould do the job.

<br />
private delegate void AddTextDelegate(String strText); <br />
private void AddText(String strText) <br />
{ <br />
     MyComboBox.Items.Add(strText); <br />
} <br />

and in your event handler:

<br />
Invoke(new AddTextDelegate(AddText), <br />
     new Object[] { strText});<br />

I hope this works.

Thanks for your help.

That "COM server" is only an OLE Automation server. It does not fire any
event. Only thing it offers is a member function that takes an int as
the handle of the combobox, and populate the combobox by sending CB_***
messages.

I am curious: after calling the COM server member function I can see
the combobox is populated with data. Where are these data stored? Any
way to get them and put them them into the Items collection?

Thanks again.

StreamWriter.WriteLine() doesn't complete on last line!

Hello everyone! Big Grin | :-D

OK, I have a program that has to find files inside of some specific directories and then add the filenames to a string array. There's like 18,000 files... My problem: The last line on the file comes cut out. I thought this was some file limit problem, so I broke it down into 2 files. Still the problem persisted. Then I went for 4. Still. Then I went to 6. STILL! Anyone know what's wrong here? The files are on a network drive, but I don't think that's it, since I've seen this problem a long time ago on regular drives. Anyone know how to fix it? Thanks! Wink | ;-)

Are you calling Flush and/or Close on the stream when you are finished?

"It worked!" WTF | :WTF:

?

This seems funny to me, because it implies that closing a file after writing to it is some kind of clever trick or technique as opposed to what you should always do.

BTW, this sounds like something you might want to do with a script (Python or Ruby, or (if you must) Perl, etc.).

Well... I remember writing to files and seeing them empty afterwards... that fixed by setting AutoFlush to true, but I hardly ever close my files... :P

what do you mean, dataset is simple, which take string/int values , just break the file and write to dataset in the required column's, do you need a sample code.

the best way to deal with XML's in C# is using Dataset's.
they are very easy to implement.
