• dev75040 URL Verification

  Pretty simple solution I would think, I just can't seem to find a way to get it done. I'm trying to find a way to verify/validate a URL address. Just the syntax is all I need to validate, not whether the site is real or not. I know it can be done through regular expressions but I've been told to use that only if another way can't be found. I've also been told that there should be a way to do it through the URI class. So far I can find a way to setup a WebRequest/WebResponse to make sure the the site exists but nothing to just check the syntax. Anybody know if there is a way to do this through something built in to .net Also, we are doing all of this in a class library so nothing we are checking is related to a GUI interface otherwise I wo ...Show All

• Michael Barrett events.

  hi all I have a method like following.. public void something() { string label1 = "myname"; string label2 = "myplace"; I have a checkbox p in here. p.CheckedChanged + = new EventHandler(pBox_Changed); } public void pBox_Changed(Object sender, System.EventArgs e) { I want to access the values of label1 and label 2 HERE. } As I said above I want to access the values of label1 and label two inside the event.. Could you pass these to the eventhandler Thank you in advance, cheers, prasad.. No, the event args are passed by the code firing the event, which exists in the CheckBox class. Your best bet is to move the declarations of label1 and label2 out of the something method and make th ...Show All

• boothwine Method Overloading

  I am new to .Net and am learning as I go. The .Net framework guidelines (and a few articles) encourage the usage of method overloading and ParamArrays. What is the motivation for this  I have found that overloading makes it difficult to provide new functionality in systems... for example, lets say some interface has a single method that takes an integer arument interface ISomeInterface { void Foo(int bar); } Some time later we need to add an additional parameter, a string... interface ISomeInterface { void Foo(int bar); void Foo(int bar,string ooh); } Using ParamArrays seems ambiguous to me. What is it about using structs/objects that is discouraged   ...Show All

• NeilL Create a new object through the property grid

  My apologies if I didn't label this subject appropriately. I couldn't think of anything better to put as the title. I don't know if this is even possible, but I figured this forum would be the best place to find out:) I have a property: [ BrowsableAttribute ( true ), ReadOnly ( false ), TypeConverter ( typeof (System.ComponentModel. ExpandableObjectConverter )), Category ( "Inherited Physical Values" )] public Shapes. Shape Shape { get { return _shape; } set { _shape = value ; } } The Shape property is from a parent class, "Physical" and is inherited in many child classes. The Shape class is obviously an abstract class which has m ...Show All

• Alexey Rokhin How to use the controls from another form in form I working in.

  I have problem, I was using the Visal Basic, and now have to migrate to the C#. Its not a problem. But in first steps with C# I have found a few diferences from VB. One I cant solve. For example in Form1 I have a TextBox1 and a Button1. I enter in TextBox1 "sviec", and click the Button1. Then opens the Form2 with Label1 on it and label says "sviec". In VB the Form2 code looks like this: Public Class Form2 Private Sub Form1_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase .Load Me .Label1.Text = Form1.TextBox1.Text End Sub End Class So how I can translate this Me .Label1.Text = Form1.TextBox1.Text from VB to C# Thank You! ...Show All

• Walter Luszczyk Why do we need Interfaces?

  Hi, I am not able to understand the significance of the interfaces. Interfaces exposes some behavior through methods, but classes can also expose its behavior through public methods directly, then why do we want to use the interfaces is it just for an assurence that all the methods in the interfaces are inplemented in the class Is there any other reason like performance I guess interface object will/can not be created at runtime, is it correct if so then how does the communication happen at runtime any thoughts/links to understand "what an interface is ". Thanks and Regards, Benin. Thank you. Now I could think of the uses of Interface somewhat. I got one more doubt, How does it differ from an Ab ...Show All

• install Intellisense Failure In VS.NET 2005 TS

  This is the third time this has happened this year and usually a full re-install is required to get it functioning again. This particular time this will not even work. Intellisense has completely stopped working in ALL project types (C#) inside of Visual Studio. All of the previous methods of fixing it have not worked. Here is what has been tried already: Deleted all of the obj and bin directories and recompiled the solution. Cleared out the VSWebCache directory in Documents and Settings\%Username%\ Cleared out the Temporary ASP.Net Directory under the Windows\Microsoft.Net\%Version Number%\ folder There are no syntax errors listed in the solution and it compiles with no errors and no warnings.

• Nilesh Meshram VS ComboBox missing display

  I while back I wrote a C# program using (among other things) a downdown combobox with items loaded using the .Items.AddRange() function. All works fine on my computer, but on other computers (without the VS Developer software installed), the dropdown box comes up blank. One can still select the different items through the mouse scrollwheel, so I know the data is being loaded, but the dropdown window is blank. Some of our computers have both .NET Ver 1.1 and 2.0 installed, others don't (mine specifically doesn't). The program was developed with VS .NET 2003 software. All the computers are running XP Pro, similiarily configured (though mine's the only one with the VS software), and all have the latest OS updates (I just checked). Any i ...Show All

I'm just looking for a way to change the cursor when it is over other application (i.e. windows calculator). I don't believe that C# can't do something that is possible in C/C++. You can't with C# alone. You need a dll for a global hook(s). There are a couple of examples on codeproject. Won't be a walk in the park tho.

• KvRaji How to sort rows in DataTable

  Hello! I have a DataGridView which is binded to DataTable. For database I simply use XML file. This xml file is updated (via DataTable) according to changed which are made on DataGridView. Application also works in other way - data is loaded from xml file into DataTable and populates the DataGridView. My problem is that I would like to sort data (rows) in my own way. I saw DataGridView has a Sort() function. But it is binded to DataTable so sorting rows in DataGridView is not possible. Then I tried to sort rows in DataTable but it has no sorting function... Sorting data in XML file would be to complicated... Does anybody knows the way of sorting rows (for example in DataTable) or any other way Thanks for any idea, Ziga ...Show All
