First of all I would like to thank every one who has tried to help me thus far, it great! As I said im a noob at c# getting this type of help will bring me to the next level (even if its a still a low one Wink | ;)

)

I'm am using vista....

when using Shukla's great piece of code I get this:
The problem might be missing a reference?

Error 1 The type or namespace name 'ServiceProcess' does not exist in the namespace 'System' (are you missing an assembly reference?) C:\Users\mike\AppData\Local\Temporary Projects\ConsoleApplication1\Program.cs 2 14 ConsoleApplication1

The problem might be missing a reference?
Also the ebook (Microsoft.Press.Microsoft.Visual.C.Sharp.2008.Step.by.Step)I use to teach myself is not telling me how to link in a external .dll so if you have any good references on this subject I would love to know!

Anyway thank you for you time! Big Grin | :-D

Hey,
I am programing a program that uses a Web Service to connect between the Server and WinAPP forms.

I made the web service and active my IIS 7 (Using vista ultimate), then i enterd into my localost(using IP) and all go ok (check my defined methods and they returned void XML data)

But when i combine that web service to WinAPP and them bind data to datagrid i got error:

System.Net.WebException: ‏‏הבקשה נכשלה עם הודעת השגיאה:

the code i userd

Hmm, my Hebrew is no so good, but you might try using: int.TryParse() instead of int.Parse(). Also, it is good to use some debug methods for inspecting the SOAP message before and after it is processed. You can do this in debug mode in Visual Studio. Make sure your IO is working correctly. This is the half split, method for finding bugs in SOAP based web services. Then depending on where the problem is manifesting you will know what end point is responsible for the problem.

Sorry about the hebrew... :$

Isolved the problem
i enterd in the windows form into app.config

and them edit

                serializeAs="String">
                <value>http://192.168.111.1/UniversityWebServices/Service.asmx</value>

Now, when he hav AspxAutoDectateCoolieSupport it gives me the results Big Grin | :-D

How do I check whether the "X" button in the top right corner was clicked?

I need to shut down the entire application when the user clicks this button, but I don't know how to check if the window was closed via the "X" button or some other button.

Hi,

you should have a look at the Form.FormClosing event, its event arg has a CloseReason property.

Subscribe to the Form.FormClosing event and look at e.CloseReason. If the user closes the Form via Alt-F4 or the 'X' button, then e.CloseReason will be CloseReason.UserClosing. For the rest of the possible values, look in the documentation[^]

GDI+ how to not painting the background image [modified]

cppwxwidgetsss20-Jun-09 1:44

20-Jun-09 1:44

Hello everybody
I have a Form and I use the GDI+ to have a User Interface
I have a Button(just an image) that should be repainted when it is clicked
and I use a flag at the mouse event handler to know when the button is clicked
and in the OnPaint method I check it FIRST, and if the flag was True I don't paint
the BackGroundImage, because it is painted before (at the startup of the Form)
but I don't know why that BackGroundImage is gone when the event occures
and only my button and the BackColor of the Form is shown
=>>note: I don't want to use BackGroundImage because I think it will paint it all the times that the Form is repainted, and it is process intensive
Thank you
P.S: If you want to read this code better you can copy/paste it in VS.NET and
select all the code and use CTRL + (K) then CTRL + (F) to format the code
in a good format to be more readable
here is the OnPaint method:

<br />
 protected override void OnPaint(PaintEventArgs e)<br />
        {<br />
            if (LanguageTraining)<br />
            {<br />
                //dc.FillRectangle(Brushes.White, new Rectangle(744, 617, 248, 42));<br />
                dc.DrawImage(ButtonSelectedBlue, LanguageButtonBounds);<br />
                LanguageTraining = false;<br />
                base.OnPaint(e);<br />
                return;<br />
            }<br />
            base.OnPaint(e);<br />

Hi,

1.
you can show formatted code by using PRE tags instead of CODE tags

2.
There must be several ways to prevent a background repaint.
for one I would try without the base.OnPaint() statement;
alternatively you can have a look at the ControlStyles Enumeration, and the Control.SetStyle method.

Smile | :)

hi there,
I have a simple WPF window with a button in it.
now during runtime, i pass this button control to another function, and there, i want to know the parent of this control. ie the window, with the full namespace.
any way for this thru C#

We have a WPF forum. The control has a parent property, to know the type, you can use the GetType method, you can also use reflection. Any method that gets passed a control, sounds a little ugly to me.

Hi
Because of various graphics that i use in my app, I want my app to run under Windows Classic Theme regardless of the theme the user has selected before they run my app.

Where can I find info about the API calls I need to swtich tmeme at start up and to restore to users' chosen theme on exit?

Thanks.

Swapping the whole system theme is a little user hostile. It would be better to skin your app to make it look the way you want.

Re: Selecting Color Scheme from withing app

That's basically what I want to do, but using Windows Classic Theme for the skin instead of a custom skin, but didn't think of it that way.

Now all I have to do is find out how to do it - there are a lot of articles about skinning, so it is difficult to find the best article to look at.

Open link in new Tab when Mouse Middle Click...

Hi All

I'm working on a little web browser that supports tabs and all is good but everytime I click a link that is supposed to open in a new tab or window, instead of opening a new window/tab in my own web browser that i am making, it chooses to open a new instance of the system's default web browser (Internet Explorer) and I have tried to find some articles/samples on the web but have been unsuccessful.

Does anybody know how I would go about allowing links to be opened in a new tab in the browser i am making?

Any suggestions would be greatly appreciated

thanks

Well, unless I misse the memo ( possible ), the web browser control doesn't support tabs. So, you'd have to catch the event of a page opening, swallow it, and create your own tab, and open the URL there.
