View 2 RepliesI am connecting to a Microsoft Active Directory server in a DMZ from my .net application (asp.net VB .net 4.0). I need to create a new "inetorgperson" in an orgunit called "SingleCustomerAccount".
I have had to use the System.DirectoryServices.Protocols namespace for all the work, because the ADSI classes (System.DirectoryServices namespace) wouldn't work across the DMZ properly.
Anyway it's been working fine connecting to Active Directory on Windows Server 2003 R2; however we're running tests against Active Directory on Windows Server 2008 R2 (2008r2 in native mode for forest and domain) in order to upgrade.
My existing code to create a user does not work.

the user of my application is able to run a diagnostic tool which is part of my application. This diagnostic tool searches every file on the computer, logs the names, and if the my program is able to then the file will be read.
My program has other uses as well. If the user wants to do something else in my program then i want the diagnostic code to run in the background. I don't want this code to prevent users from using other features of my application since the diagnostic search does take time.
How do i do this? Threading? A background worker? If the anwser is Threading which i am pretty sure it is, how do i set up a thread? My computer has 4 GB of RAM - 2GB & 2GB so i know i am able to do this smoothly.
When you click a button, the program should start op everytime your computer starts, but it must be in the background, so that you wont notice it.

I think it's because I have a background image. For example when I maximize the program it lags. I mean big software companies have programs that have more pixel images and are much more colorful then my program is but never lag why. AVG has nice look but the program never lag. But the code runs fine so that is a good thing. How can I stop the lag with background image?

View 3 RepliesIm trying to set a background image for my Form. The problem is that the form contains textboxes, groupboxes, labels and panels, so I have to manually set the picture for each type of objects. That looks weird though because you can tell that the same picture has been placed a lot of times for each object. Is there a solution to this?

View 3 RepliesMVC3 VB.NET application using Itextsharp. I have a section of code that generates a pdf file everything looks great but I would like to alternate the line colors in that pdf file between 2 color so that the values are easy to follow for the person looking at it. Is there a way to set the background color of a whole line based on font size to a set color? A function I would be using this in is below:
[Code]...
I thought about just setting the background color of the line by using the y_line1 and using a modulus to determine if the color should be grey or white. But I have found no code samples anywhere about how to set a whole line background color..
I have a problem when i opened a picture that
size image < size picture box
How can make the background of the picture box become an image too because my coding was to get the pixel from width and height picture box.. When I found the none image property, vb will show the error.. said coordinate(x,y) was null. It can be illustrated like on the picture above.
Sometimes I will used it when:
picture properties - size mode = center image
So the picture will found at center height and width.. and the background will surround it. Sometimes I used it after rotating the picture.. The problem occur when the picture get rotate for 45 degree. I am taking all point corners of the image and rotating it. So the picture will create 4 triangle at the corners..
Is it possible to have code running in the background and still be able to use other parts of the program (i.e. firing other events).For example I have a instant messaging chat in my program and when the user has a new message then the display flashes from green to red as seen below

But I still want to be able to continue using the other functions in my program despite having this code running in the background (which highlights to the user that he has a new instant message by changing the display background colour)How can I overcome this?

View 1 RepliesI have a class that wraps up a few methods (e.g. OpenPort, SendMessage etc.). Some of the methods accept a number of parameters and return a value (e.g. SendMessage accepts port and a string that is the message to be sent and returns true or false depending on whether the mesage was sent successfully or not). I create an instance of my class when my form loads and I call the various methods throughout the lifetime of the app.In my SendMessage method there is actually a few steps that involves a delay as I send commands to an instrument and wait for a response. I'm using the AutoResetEvent class to synchronize things. Whilst this works ok I've noted that the UI is unresponsive during the wait period.

View 1 RepliesI am working on a project and i have come to designing my splash screen... i dont want a useless one what just shows a loading bar what does nothing, im trying to make it useful and show while the main form is loading however this is proving to be a pain in the backside.. i can make the splash screen load when the exe is executed then close when the form is ready but i want to add an animation to the form (just a moving logo) this is just done by me running an timer what changes the location at each tick.. i can get it to work well on its own but when i add frmMain.show() to the code to load the program the animation will not work... i only get this when i ask the program to load the main form..

"ActiveX control '' cannot be instantiated because the current thread is not in a single-threaded apartment." On search i found a link :Forum Link
But still in this link Firstly i dont understand where to insert this snippet and secondly how to implement the idea on background worker.
Is it possible to start an application not being visible? This application is a batch application and my application would look way better if I could hide this batch.
