I'm not able to use edit and continue feature while debugging my project. I'm using VB 2008 Express Edition on a 32bit winXP version.
I already check on MSDN and found that this feature can be enable in dialog Tools/Options/Debugging.... However, I do not have a Debugging entry in the treeview in this option dialog. I also used to reset the Import/Export setting features in the tool menue. However this did not solve the problem as well. Then I tried to import some settings and I was able to select the option for debugging. However in the tools/option menu, the debugging feature is still not visible. Edit and Continue is not working as well
Its really a pain to debug with the current setup, as I always have to restart my application when I did some minor changes.
I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

When I click on the icon of my program it shows the error message

View 2 RepliesI've a vb.net (VS2005) destop application, which uses faxcomlib to send fax. Fax server is a windows 2003 server. when i run the vb.net application on the server, it uses the local fax service and it works fine. however, when i run the appllcation from a windows XP client, the fax dosen't work. it is not able to connect to the network fax. i've also read somewhere that faxcomlib only works with windows 2003 or SBS server. if yes, then the best way to send fax in such an environment where fax is installed on a Windows 2003 server and the client machinces are windows XP or Windows Vista.

I have a MDI form that has a child form that is opened by default when the application loads. I also automatically maximize the child form.

I have one tool which we developed on visual studio 2010. there are basically two parts of my project, one is UI part which i wrote in VB and algorithm part which is in C++ on back end. When we compile C++ part it creates a .dll which is used by my front end VB program.
Now my problem is little weird since i am compiling and deploying this tool on windows xp machine but some of the users are using windows 7 64 bit machines and after running the program for about 5-10 minutes, it crashes on windows 7 with following error
Not enough storage is available to process this command and when i view details of that error, i get the following description.

I have a standard Visual Studio 2008 VB.Net WinForm application, running on Vista Business. One of the forms has a timer that passes Me.Handle to FlashWindowEx. This works as intended as long as none of the windows that belong to this application are the Foreground window. If this program is running and another application's window is the Foreground window, then it flashes as intended. If, however, any of this application's windows are the Foreground window, then it doesn't flash.

View 6 RepliesI have a VB project that I created a simple setup project to deploy. It installs fine except for one problem. It crashes because it can't read its own application directory. Included with the program are an xml and schema file that it needs to read when starting.dditionally it may create a log file, also in its application directory. Either of these will return errors under the default install. This was not an issue when running the program in VS and if modify the program to work with another directly like C:Temp. I have a workaround in which I change the permissions of Users group to Full Control for the application directory
View 7 RepliesI have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

View 2 RepliesOkay. I have a TreeViewBooks that displays 'OT' and 'NT' as root nodes. They both have child nodes, but for sake of length lets just use 'OT' as an example. Under 'OT' I have childnodes that are the names of the books of the Bible; Genesis, Exodus,etc. Under the childnode 'Genesis' I have other child nodes that represent the Chapters in the Book of Genesis. Ex: 'Chapter 1', 'Chapter 2' etc.What I need to figure out is how to display the correct Chapter the user has chosen. Let's say they choose Genesis Chapter 1. I want Genesis Chapter 1 to be displayed in the RichTextBoxDisplay.

So I have 2 data files, single dimension, that I'm trying to populate two rtb. If I comment one streamreader out the other will print. This also works in the vise versa situation. Does anybody see where I'm going wrong with this? They won't run together.

dim str as nullable(of string) is this syntax incorrect?
