I could review that could help me create a designer view (actually similar to how Visual Studio works but more basic), I would like to be able to add controls dynamically (just panels or images), then move those around individually(drag and drop), then count them all and get an array of what I have added..[code]But I would like to get an idea how it looks if things get more complicated..I wonder, are we able to use the classes of Visual Studio's editor in some way? Or are there .NEt classses that can do this?

View 1 RepliesI am looking to make a database call based on user input. The line I am using is:general_read.CommandText = "SELECT * FROM general WHERE Business_Name = '" & business_name & "';"
business_name is dynamically loaded from:Protected Sub btnLoad_Click(sender As Object, e As System.EventArgs) Handles btnLoad.Click business_name = txtName.Text
[Code]...
The error that is being shown is: Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.I'm assuming it has something to do with the variable not being set before the database call is made, but I'm not entirely sure.

WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].
I guess this is a reference issue, but I have added references to WMP libraries (axinterop.wmplib.dll and interop.wmplib.dll). The WMP works on the XP machine, but not when called from my application.I have searched the web now for 5 days and changed references, and reinstalled the media player on the XP machine, but nothing works.
I have seen this happen before but am not sure how I resolved it in the past. On runtime the controls of my form change from the windows 7/vista format to an older version format as shown in the attached image.

I am in the process of developing a messaging framework for a windows application that sends messages to a java application. To be precise when the win app wants to send a message it simply drops the message in a common database table which will be picked up by the java app. The windows application is deployed across 10 application servers (10 instances) over citrix for load balancing.Each instance of the application is capable of sending a message to the java application and each of these messages should have a unique id. From my end I need to make sure every message generated has to carry a unique id so that they can be identified when necessary. All the messages can be cleared every day or two.i am not quite sure about a best method of achieving this. Initially I wanted to create a static method that serves the next available id (incrementing the last id by 1). But this approach willn't guarantee unique number as the application starts only when at least one user is logged on. For e.g .On one server the app starts when a user logs in, he then sends a message and then the application stops when that user logs off. So when a next request for the app comes to that server a new instance will be started.
View 3 RepliesI currently have a simple crystal reports application which generates a crystal report and in the built in viewer provided by VS2005. There is a drop down where you can select options to change the criteria of the report. I wish to convert this app to a windows executable which will take all those select options and generates pdfs based on the crystal report. the executable will be triggered by windows task scheduler...or maybe command line app?
Obviously this will be somewhat of a re-write. What would be the best way to start this as? a crystal report application or a windows application.
I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?
i made an application for serial communication. for this application i need to set delay time. during this delay time i m doing some other task.
