WebDAV & Exchange 2003 - Works In Debug, Fails Without?
Sep 23, 2010I am writing some code in VB.Net under .NET 2.0 which interfaces with MS Exchange 2003.Because of the Exchange 2003 "requirement" I am forced to write this code using WEBDAV.The code itself is replicating, to some degree,a schedule management process.It's creating Appointments on the Exchange Server in response to inputs from the user and managing it's data internally in a SQL Server database.The problem situation is this: A new person is assigned to be in charge of a meeting. The requirement says the program should generate a meeting cancellation request to the person removed from the meeting (if such a person existed) and a meeting request sent to the new person.In the case of there being an existing person, what appears to happen is this:
The meeting cancellation request
gets sent Exchange barfs and returns status code 500 (internal server error) during the set of requests which send the meeting request to the new person.However! While debugging this particular scenario, it works just fine for me, if I step through the code in the Visual Studio debugger. Left to it's own devices, it fails every time.Just for yuk's sake, I added a Thread.Sleep(500) to the part after sending the cancellation request, and Exchange doesn't barf anymore...
So, my question! If adding a Thread.Sleep to the code causes this error to go away, a race condition is implied, no? But, my code is running under a web application and is a totally single threaded process, from start to finish. The web requests I am sending are all in synchronous mode so this shouldn't be a problem. [code]....
...but a lot of the implementation details are hidden here, as I wrote a set of classes to interface with Exchange WebDAV.

Mar 9, 2012After compiling the project it works fine on windows 7 32bit and 64 bit but will not work on server 2003 or xp clients have not checked vista yet, i have verified that .net 4 is installed and i can tell you that i do not get an error message when installing apart from the icon that i have given the project does not appear and is a blank icon on the desktop. When i try to run the program it will try to start i see the service in the task manager and after a while it will error out and crash. I can see the memory usage go from 20,000K to 70.000k.

.NET Works But Not C#
Feb 26, 2012I have created lots of applications with visual basic 2008, tested them on many other computers, worked like a charm. After I moved to 2010, all my applications compiled, ran without a problem even on different machines (worst case scenario was that some older PCs needed the 4.0 framework to be installed first). Anyway suddenly I ran into a very weird problem which I cant figure out.I have Visual C# 2008 (Express Edition) on this machine installed and everything ran/compiled flawlessly but when I tried the application on a different computer, it can't even start. It crashes as soon as you attempt to run it and displays that 'Application Stopped Working' error.
I also tried to compile it as Release, then start the exe .. still the same problem. Sorry again for asking this on a VB forum, I just started playing around with C# after VB and didn't know where to ask.Aditional Info: Visual Basic 2008 and 2010 programs work perfectly on the same machines on which Visual C# 2008 doesn't. (I would be glad if some one could at least re-direct me to somewhere else )
SQL Works MDB Does Not?
Jul 21, 2009UserLogin.zip Starting off with a very simple user database with encryption based on [URL]..Updating to an SQL database WORKS FINE using the SqlDB classes. Updating to a 2003 Access MDB DOES NOT - when I use OleDB Classes. They are almost identical. I am getting an error ""Operation must use an updateable query", but all the articles on this do not seem relevant. I need to get the MDB working.

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.now i think it means that it cant find the mysql connecter and data and stuff but the user shouldn't need to have that right? it should come with the app to make it work for everyone

MapDrive Works Sometimes/sometimes Not?
May 21, 2009Not sure if this is the right place to post this, but the VB Script forum seemed only for inet apps. This is a script that runs when a user logs onto windows to map network drives.The PROBLEM: When a user logs into Windows on our network, this script runs, but sometimes it does not work. There is no MsgBox and the network drives do not map. However once Windows is loaded completely to the desktop, you can run the script and it will map the drives.
Does anyone see anything wrong with this code?? I did not write it, but am in charge of finding out why it is woring sporadically.

View 7 RepliesSetWindowsHookEx Works In Net 2 But Not In Net 4
May 24, 2010I am developing an application that will engage a bar code scanner and will need to be listening for input even when it is not the active application or from a separate thread from within the application. I can get a handle to the hook when I set the project to compile for Net 2.When I set my project to compile for Net 4 I cannot get a handle from the SetWindowsHookEx.Same code, no changes at all.While obviously I can get a working DLL out of this it really is buggin the out of me.Additionally, if one of my colegues needs to adjust this DLL in the future and does not know, they may compile it in Net 4.I also have no idea what will be the effects if I reference this DLL in another project that is compiled in Net 4.Lastly, I am worried that I may encounter more difficulties like this in the future if I cannot figure out what the difference is.[code]

.net - Split Function - How Does It Works
Feb 10, 2012I'm trying to get split to work.Here is my code
Public Sub CheckUpdate(ByVal FileURL As String)
Dim instance As WebClient = New WebClient
Dim ApplyTo As String = instance.DownloadString(FileURL)
asd = ApplyTo.Split(",")
End Sub
I use it like this
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
NewUpdate.CheckUpdate("version.txt")
Label1.Text = NewUpdate.asd(0)
End Sub
(yeah I know i use it on local txt for now!)So with asd(0) it reads the whole file. If i check asd(1) I get IndexOutOfRange . So how does Split() work?
.Net Windows Application - How It Works
Jul 20, 2010We have an application(.exe), longtime back some developer wrote the code and now he is not with the company. I happend to be support this application. I have to do some modifications in the code.I have a .vb file and .Config file with me. The .VB file is calling a SSIS pkg and doing some dataload and creates some files and it formate the file names what it generates and it send emails to large group of ppl.I have opend the code in Visaulstudio but i do not have any option to debug or do some breakpoints.How can I use this config file?Do I have to add both of them in the project? To debug I need SSIS pkg as well so do I have to add all these 3 of them into my solution?I know where to change the code, after changing the code how can I create a application EXE file?
View 6 RepliesC# - AutoResizeColumnHeadersHeight Only Works Set A Breakpoint?
Feb 3, 2010Using VB.Net I want to automatically size the height of the headers in a DataGridView so I am calling AutoResizeColumnHeadersHeight during the form load after the data has been populated.
The method doesn't appear to do anything, but does work if I do the following:
- put a breakpoint on grid.AutoResizeColumnHeadersHeight()
- open quickwatch on the grid
- expand the child properties
- close quickwatch and hit F5 to continue processing
The resizing then works I assume the reason is that evaluating one of the properties of the grid is causing the method to behave differently. Does anybody know either what I should be doing differently, or a workaround - e.g. which property do I need to evaluate to make it work?
Code Still Works Even After Deleting It?
Aug 15, 2011I don't think the problem lies within the codes but..The last thing I did was use datediff.. and show the result on a label.. and when I wasn't satisfied with the result I changed a few lines, and I noticed it was still the same whenever I run it.I've tried changing/deleting the codes to my forms but whenever I run the program, it still works. I even tried deleting the form and it still works.
