Hi,
I have written a web service and need to connect to that using win form. In Visual Studio 2003, when I try to add web reference using LAN IP, it works. But if I use internet IP for the same service/server/IIS/machine, Visual Studio gives a prompt for "Discovery Credential For Proxy Server".
What I need to provide there, or how can I get rid of this, please help.

richTextBox1.Text += message + "\r\n";<br />
int pos = 0;<br />
while(pos < richTextBox1.TextLength)<br />
{<br />
int index = richTextBox1.Find(textBox1.Text,pos,RichTextBoxFinds.None);<br />
if(index == -1)<br />
break;<br />
richTextBox1.Select(index,textBox1.Text.Length);<br />
richTextBox1.SelectionFont = fontDialog1.Font;<br />
richTextBox1.SelectionColor = colorDialog1.Color;<br />
pos = index + RichTextBox1.TextLength;<br />
}<br />

That's because you're using Find to find the sentence in the text and it obviously is finding both the first and the new sentence. I'd suggest using another variable to store the *previous* index, looping till the last Find (until index returns -1) and then using the previous index to set the color stuff. Or, if there is something like LastIndexOf, you could use it.

Not compiled or tested, but you'll get the idea.
string message = "Snouto : " + textBox1.Text;
richTextBox1.Text += message + "\r\n";
int pos = 0;
int prevIndex = -1;
while(pos < richTextBox1.TextLength)
{
int index = richTextBox1.Find(textBox1.Text,pos,RichTextBoxFinds.None);
if(index == -1)
break;
prevIndex = index;
pos = index + RichTextBox1.TextLength;
}
index = prevIndex;
richTextBox1.Select(index,textBox1.Text.Length);
richTextBox1.SelectionFont = fontDialog1.Font;
richTextBox1.SelectionColor = colorDialog1.Color;
textBox1.Clear();

Hi,
I am trying to record the user actions on forms as part of my exception handling.
I've set up a singleton object that records all the control events i'm interested in and it works fine for the single test form. The form registers itself in the constructor and unregisters itself on disposal.
Then i thought i'd be clever and create a base class, let's call it myFormBase. I put the line to register the controls in the constructor:
_controlWatcher.AddForm(this);
ControlWatcher takes an argument of type form, i've also tried type myFormBase, but when i look through the controls for the form I only get the controls present on the base class, not the controls on the actual form i have passed in.
Is there a way round this problem?
Thanks
Russell

You would need to have them, atleast as abstract properties, in the base class. Something like
abstract class MyFormBase
{
public abstract TextBox MyTextBox
{
get ;
}
}
class MyForm : MyFormBase
{
private TextBox textbox = new TextBox();
public override TextBox MyTextBox
{
get { return textbox; }
}
}
Or if all classes deriving from MyFormBase would have those controls, you can as well declare them in the base class itself.

I was trying to loop through the controls collection on the form rather than refernce controls directly. I think it was laziness on my part, i'll put a call in each form i create, instead.
Thanks for your help Senthil,
Russ

I have a newbie question about threading and controls,
I know the rule: "A control can not be accessed from a thread that is not the creator of that control"
But if I create a class which inherits from Form, and add new members which are not controls, can I access those members from any thread?? 
Thanks in advance
Use the force

Yes you can, you need to worry only about accessing/modifying controls. But you might still want to synchronize access to them using the lock statement.

This is driving us mad, i'll try and keep it simple.
We have a custom control writtten in VB.Net compiled as a class library, this is added as a reference to a C# application, with the control being placed on its form.
They both have the same/similar root namespace eg:
CompanyName.Things.<the thing="">With me so far...the problem is that if at anytime after the component has been referenced the custom control changes, say for example adding a style enum to the control that can be set by designers, the forms that use this control complain about not being able to see the additions.
This is *most* true for our custom properties of the control that can be set by the designer.
Removing and re-referencing the component makes no difference, and of course i am sure the features being added are public available.
It seems (prove me wrong) that once a VB.Net custom control has been added to a C# application you can't make any changes to that custom control! That can't be correct surely.
I don't seem to have this problem if the custom control is written in C#.
Am i mad, what's the problem?

How are you referencing the VB .NET library? Did you add it by browsing and selecting the dll (binary reference) or by selecting it from the Projects tab (in VS .NET) ? If it is the former and if Copy Local is set to true, then Visual Studio won't watch for modifications to the library, instead, it will simply use the local copy (that's what Copy Local does). My guess is that you added it as a binary reference, whereas for C# controls, you had them in the same project and therefore added them through the Projects tab.
You can try setting Copy Local to false (Right click on the reference in VS .NET, click Properties). Or, if the changes are very infrequent, you can manually copy the library to the C# project's bin/debug directory (or do it as a PreBuild step).

Senthil

Yeah its added as a binary reference.
Right i'll get the guys to try your suggestion out, i see what your saying, and thats worth a try.
It does seem to be more when you look at the designer of a form containing the controls, though.

I have run time generated data table and table style including numerictextboxColumns. I set datatable to datasource of Datagrid1. Before setting datagrids table style, user can move on cells with tab key , after setting table style, when user try to move on datagrid with TAB key, cursor jump 2 cells not one :S
What s problem.

You will have to override the PreProcessMessage of the DataGridTextBoxColumn and NumericUpDown. There you can control the TAB key. Look for this method in MSDN. If you want I can post some code snippet.

I have an API function like this:
void theFunc(LP_STRUCT theStructPt);
theStructPt is a pointer to struct STRUCT.
I want to use it in C#, so I have this
[DllImport("myDll.dll", EntryPoint="theFunc")]
public static extern TheFunc(IntPtr theStructPt);
I call the function and the theStructPt pointer point to my required struct now. But I dont know how to convert the memory where theStructPt point to to struct so I can use it. I want something like that:
MyStruct str = (MyStruct) theStructPt;
str.var1 = "hello";
str.var2 = 5;
Anybody help me! Thanks alot

Did you try this?
public static extern void TheFunc(ref STRUCT theStructPt);

Hello
how do i create a new RadioButton in run time?
i getting a list of name would like to create a radiobutton on the form within a panel .
when i try :
RadioButton rbNew = new RadioButton ();
i get
Embedded statement cannot be a declaration or labeled statement<br />
please advice
thanks
Have a nice Day

Searching for the error brings up that you maybe put the statement inside of an if-statement, which isn't allowed. Try the following instead:
RadioButton rbNew;
if (something)
{
rbNew = new RadioButton();
}
If this doesn't help, please provide the surrounding code.

hi
How can i add user control in class library
|
|
|
|

Hi
I have to work on multithreading concepts in c# windows application.
Design a form with 3 labels and 3 text boxes and a button.
I should enter the time in three text boxes. Three different times. And press the Button.
Label 1 should become green color after the entered time period in text box1.
Label 2 should become Yellow color after the entered time period in text box2.
Label 3 should become Blue color after the entered time period in text box3.
I should have three threads to start three processes. Start the three threads in the button click.
Thread 1 to start the thread and wait for the entered time in text box 1 and make the label 1 green. And so on.
U should enter the time in milli seconds. 1 second = 1000 milliseconds.
So if I want to enter 5 seconds. I should enter 5000 in the text box. I should Write a windows application for this.
Pls anyone explain me how to do this . pls help me to do this sample.

I'm no expert in Threading but i could accomplish the same task without explicitly using threads. I used the Timer class.
