Creating a call stack diagram We have just recently been thrown into a big project that requires us to get into the code (duh). We are using different methods to get acquainted with it, breakpoints etc. However we found that one method is to make a call tree of the application, what is the easiest /fastest way to do this? By code? Pl...
When using databinding in WPF, the target dependency object gets updated when it is notified that the source has changed through the INotifyPropertyChanged interface. For example: <TextBlock Text="{Binding Path=SomeField}"/> The text field will change to correctly reflect the value of SomeField whenever PropertyChanged(this, new Pro...
I need to access the current and previous element in an IQueryable object. If I had an int array, I would do the following: var array = new int[]{0,1,2,3,4}; for(var i = 1; i<array.Length ; i++) { method1(array[i-1], array[i]); } I don't know to do the same with IQueryable, since it does not implement IList. ...
Hi, I have been getting more and more sick of all the quirks about control ids, trying to get your data in serverside (based on client-side events). I seem to spend more time fighting with controls in asp.net, that I think it takes me more time than I gain by using it. I was thinking about using plain html/javascript with jQuery and a w...
Hi, I was reading a couple of articles a while back which I think described a behaviour where you can, in a .net application (specifically VB.net), allow an exception to occur, and then handle it in some kind of application-level exception handler, as opposed to within a Try/Catch block. My google-fu is weak at the moment, so I'm not hav...
I'm trying to learn LINQ to SQL and i've found out about the LoadWith function. All the examples i've found will load all records from the table you specify in the LoadWith function e.g. var dlo = new DataLoadOptions(); dlo.LoadWith<Blog>(b => b.Posts); this.LoadOptions = dlo; What I would like to know is if it's possible to load in t...
In my WPF form I have a textbox. When a timer elapses, the content of the textbox needs to be fetched. The timer elapsed is working in a different thread then the UI. The question is kinda two-fold: What is the easiest, most readable way to read the value from a GUI thread cross thread (I found several and they look too verbose for wh...
Does C# allow you to add a String to a RowHeader in a DataGridView? If so, how is it accomplished? I'm writing a Windows Form to displayed Customer Payment Data for the year so far. The ColumnHeaders display January, February, March, etc... and rather than have a blank column with DateTime.Now.Year I would like to put it in the RowHead...
I have a generic class that I am using Reflection to pull out the properties of the type of the generic and looking for an attribute. I am recursing into each property to do the same for each of their properties. My issue is when I come to some sort of collection property (property that is a collection) or ICollection property. I will...

The form will submit if I enter the first folder name into textbox1 and click the "Add Folder" button. When I submit multiple folders with the same name the output should be an indexed increment of the na...
I have a problem where in I have to call into the AS400 db2 to call a series of insert/update stored procedures from my .net and then update a few SQL2005 tables if everything in the AS400 db goes ahead fine. The driver I am using does not have distributed transactions so I was wondering if you can use any of IBMs iSeries Drivers for DB2...
Recently I was talking with a friend of mine who had started a C++ class a couple months ago (his first exposure to programming). We got onto the topic of C# and .NET generally, and he made the point to me that he felt it was 'doomed' for all of the commonly-cited issues (low speed, breakable bytecode, etc). I agreed with him on all thos...

Questions: Should I merge these two into the same .chm file? What is a good way to merge them? I need to exclude certain classes/packages. How ...

I'm working on a new C# application using WPF. I was under the impression that WPF was vector based and that text/buttons would be drawn in a resolution independent way. When running my application it’s fairly obvious that my application isn’t being drawn using vectors. Some of the text gets fairly blocky, and when using the windows magn...
I wrote this on a simple ASP.NET page: jQuery(document).ready(function() { jQuery("form").submit(function() { alert("kikoo"); return false }); }); and when I submit (by clicking on a button, link, ...), I never see the alert box. Is there something in asp.net page that "bypass" the submit (I think about the dopostback javasc...
