• Will Merydith Checklistbox problem in new domain...

  Hello, I have a window app written in c# that contains checklistbox. I had the statement clearselected() to clear out the checked checkboxes when the user loads the new case... Everything worked perfectly until my users got converted to new domain. Since they got converted to the new domain, the checkbox is no longer cleared out on pageload. Whatever the user selected in the previous case remained checked for the new case. The problem is: the application will not do anything because there are nothing actually checked (the checkedindices collection is actually cleared)! The user either has to shutdown the app or manually uncheck/recheck the items in order to add them to the checkeditem collection. The situati ...Show All

• Alan Adams Win To Web

  Hi, Is there any way to convert a windows application to web applicatin. i.e. I have a windows appliation, I want to run it in IE. I have heard that using ActivX it is possible. Yes, IE can host ActiveX controls. Now, converting a Windows app to ActiveX is *not* easy. And you need to make sure that the client does allow ActiveX components to be downloaded and activated, realistic only if you control the clients. As long as you're rewriting your Windows app to squeeze it into an ActiveX control, you might as well consider ASP.NET... ...Show All

• Fistandantilus282303 Difference between isEqualTo() and "=="

  Hi all, I have doubt about difference between == and isEqualTo method in C#. actually, Equals() determines whether the specified object is equal to the current object. http://msdn2.microsoft.com/en-us/library/bsc2ak47.aspx == is for reference types to see if one object references another (other than a string). If its a string, then it compares the values of the strings http://msdn2.microsoft.com/en-us/library/53k8ybth.aspx Well, they should be totally same. With 3rd party classes, this cannot be totally assured, but convensions recommend that class implementers first implement Equals method, and use that method when implementing == operator. In .NET classes, they are all the same. ...Show All

• Eric Best Call Method by Name

  How do you call(inside the class itself) a method of a class using its string name Something like: for(n=0; n<10; n++) {"MyMethod" + n} Cool! The J# assembly vjslib.dll has some neato stuff as well. Highlights I see are java.math.BigInteger and BigDecimal for arbitrary precision arithmetic, java.util.Random for advanced random number generation and java.util.zip.ZipFile to handle .zip archives... The Microsoft.VisualBasic.dll assembly has the CallByName method . Hope it doesn't turn you off too much but it *is* the power of .NET to have that available. To use it, you'll have to add a reference to the assembly... question - why would you want to do this a ...Show All

• humble.apprentice Extract image in the WebBrowser control?

  Hello, Is it possible to extract all the images that showed in the WebBrowser control into files Best regards, Eric not entirely. why dont you just use the ShowSaveAsDialog() in the webbrowser control to save the document to disk if you need the images, you need to go through each element/tag and get that image and perhaps use httpwebrequest/webresponse class to download that image and save it. Maybe use something like Document.GetElementsByTagName("img"), which returns an HtmlElementCollection of tags, then go through each one and check either the inner/outerhtml text or something to obtain the url. to make life a bit simpler, once you get the tag/image link, load i ...Show All

• alwayscnfsd Converting a string to an object reference?

  Hey guys, I have a text box thats named texBox1. I need to get this text box's text, of course using textBox1.Text but the problem is the name of the text box is defined by a variable... If MyVariable == 1, then I need textBox1, if the variable is equal to 2, then I need textBox2... etc. So to fix this, I tried converting to to a string; "textBox" + MyVariable.ToString() This works ok, I now have a string of the name of the desired text box. But how do I access its text from a string I'd need to transform it in some kind of reference to textBox1 from the string :s. The only to do this that I can see is String.System.IConvertible but I dont understand its working. So if anyone had any idea how to do this, it would be apreciated. T ...Show All

  Hi all, i have a class called ActivityLog.cs and this basically creates a log of whats going on in my console app. i construct it like: ActivityLog Activity = new ActivityLog(); then you use it like activity.log("this is one entry"); and when the program is done you can mail out the log like activity.Email("me@me.com","me@you.com","the log file"); My program uses three different classes, right now the activity log only works with the first, well it will work with all three but only if i construct a new log file for each class, i was hoping someone could help me figure out a way to pass the log back and forth during the execution of the different classes.

• johngccfc adding single quotes

  Does anyone know how to add a single quote character in the subject line of an email like this "hello 'XXX YYY' " I've tried every thing, escaping a character, character entities etc but all in vain. Please help. Any suggestion would be greatly appreciated. Thanks in Advance Shine I wouldnt understand why you need a backslash on the single quote. It works fine. It's not a special character for C#/Compiler. if you are looking to include quote marks (double quotes) then you need a backslash: MessageBox.Show("\"hi 'XXX'\""); it should work... string theSubject = "hello 'XXX YYY'"; Try this: "hello \'XXX YYY\' " Put a slash before ', during compilation, com ...Show All
