Hi,
when reading a number in a TextBox with VB.NET i use:
Number = Val(TextBox1.Text).
How can this be done in C#
Thanks for any answer

|
|
|
|
int myNumber = int.Parse(TextBox1.Text);
or
double myNumber = double.Parse(TextBox1.Text);
Just choose the right data type (int, float, double, ...). Then using method Parse.

How about :
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"C:\Test.Xml");
|
|
|
|
|
That is not faster at all.

Well the super-fast method would be read them same way as plain text. Maybe XML is not good format for your application? If you want to, provide more details about that XML file and app...

Hello everyone,
I am trying to create a media player. Right now I would like to add a control panel with images representing "Play", "Pause", "Stop", etc. I am not sure what is the right way to go about this. I tried a "menuStrip" which was dokced to the button of my winform but that doesn't seem right.
I have come across "User Control" and I was wondering if this is the right way to get this done.
truly appriciate your help in this issue. Thank you very much and have a great day.

Why not simply using delegates?

I'm having difficulty adding hidden text to a RichTextBox. See case2 below.
Case1:
Initialize Form1 in Main(string[] args){}.
In Form1, initialize a RichTextBox as follows:
RichTextBox rtb = new RichTextBox();
Observe that rtb.SelectedRtf is initially set to "{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang1033\\uc1 }\r\n";
Now try:
rtb.SelectedRtf = @"{\rtf1\ansi " + "visibleText" + @"\v " + "hiddenText" + @"\v0}";
result:
rtb.Text = "visibleTexthiddenText" as expected.
Case2:
Form1 is initialized as an MDIChild Form:
Again in Form1, initialize a RichTextBox as follows:
RichTextBox rtb = new RichTextBox();
This time rtb.SelectedRtf is initially set to empty string.
Try:
rtb.SelectedRtf = @"{\rtf1\ansi " + "visibleText" + @"\v " + "hiddenText" + @"\v0}";
result:
rtb.Text = "visibleText"
i.e. the hidden text is not being updated when Form1 is an MDIChild.
Anyone know the cause/walkaround? Your help is appreciated.
Thanks, B

I am facing the same issue. Its been 5 years since you have asked this question. Did you get the solution ? If so, please share with me.
|
|
|
|

As I recall an external component was loading a different version of the riched32.dll/riched20dll. Workaround was to initialize the right dll first (new RichTextBox() in your application).
Hope this helps.

If you perform an update, you can catch this with a trigger. How you want to proceed beyond this, is entirely up to you, but I would start with defining a trigger.
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer

I want to know how to reduce the color depth of a Bit Map Image in c#.
Then the resolution will be less at the same time the capacity of the image also will be reduced.
Then it is easy to send the image throght network due to the low capacity.
Hope thee will be some one who can give me a clue.
Thank You

All of those <Item href...> take up a lot of space, is there a way instruct .net not generate it?
This is the declaration over the webservice C# class file;
[WebService(Namespace=Constants.NAMESPACE), ToolboxItem(false), SoapRpcService]
The web method just has plain, [WebMethod] attribute and that's it.
Thanks,

I had posted this question two weeks back but till date no one has responed. Is this indeed an issue with the combobox? I hope I'm clear with my question and this time I will get some help from this forum.
ComboBox control has got selectedindexchanged event. As the name suggest this event should fire when selected item change for the combobox. But this event fires even when the currently selected item is selected again from the dropdown list of combobox.
e.g.
if I have loaded following items in my combobox say
item1
item2
item3
item4
with item1 as selected when my application starts.
Now if from UI, I again select the "item1" (which is already selected in combo box) then also the selectedindexchanged event fires. In this case the index has not changed still the selectedindexchanged event fires. I find this bit strange.
Is there anyway to findout when the selected item has changed by User. I want some kind of notification when user indeed changes the combobox selected item (not when combobox.selecteditem is set through code)?
regards
KC

You have to store your selected index, and compare it to what is in the control after the event fires. The event should check first, then store the value for next time.

Thanks for your reply. I agree to your solution where I have to remember the previously selected index and match it with the newly selected index in the eventhandler. If new and previous indexes are same then skip the execution of handler. But this is not going to serve my purpose.
What I want is, I want to skip the execution of ComboboxSelectedIndexChanged Eventhandler when the already selected item in the combobox is again selected by user (i.e. user clicks the combobox and select the same item again). I don't mind if combobox SelectedIndex changed event fires through some code i.e. ComboBox.SelectedIndex = 2;
So in nutshell want to restrict the eventhandler when same item is selected through user interaction.

Well, you plainly can't stop the event from firing. Until it fires, you can't make your code run at all.

You could combine it with TextChanged event
