I've written a really simple launcher app for my team at work to use. However I wrote it in VB.net Express 2010 so its using .NET 4. I need it to be compatible with older machines that are using .NET 2 or maybe 2.5. I don't want to force upgrading to a higher .net if its not needed. And in some cases we work on old machines that can't be upgraded. My app is really simple and I'll post the code if needed. I am still a noob, my coding is ugly, and this is a quick and dirty tool.
View 1 RepliesIs it possible to change the application version without publishing the application? Because I'm going to make an auto updater which needs some version information to work, but I don't want to have an installer.

I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

I would like my program to overwrite its previous version such that users don't have to uninstall the previous version before installing the new one.
I'm guessing it has something to do with setting Publish Version (Major, Minor, Build, Revision), Assembly Version or File Version.

I have a BaseClass, a DerivedClass1 and a DerivedClass2 from a third party library. DerivedClass1 and DerivedClass2 both inherit from BaseClass.There's a ContainerClass, from the same library, with a member variable ActiveItem, which can be of DerivedClass1 or DerivedClass2, so it is declared as BaseClass.I want to know if ActiveItem is of DerivedClass1, as it can change in runtime without notice.If I do
Dim isDerivedClass1 as boolean = TypeOf(oject.ActiveItem) Is DerivedClass1
then I get a compile time error, telling me that ActiveItem can never be of DerivedClass1 type.I have tried several combinations of GetType and TypeOf but it doesn't seem possible to check this. I have also tried to declare an auxiliary DerivedClass1 variable and comparing their types, but haven't got any luck either.
Edit:The following code doesn't compile in vs2005 SP1.

View 18 RepliesI need to build a comma-delimited string from an array.
For i=0 to ubound(arr)
str+= arr(i) & ","
Next i
The trouble is that I end up with an extra comma at the end.
My current method for removing the comma is:
If str<>"" then
Left(str, Len(str) - 1)
End if
But it seems pretty untidy, and non-generic. I have to do this so often, it's become a pain.
I have a system that has a gridview on one page with an Update Panel. On selection of one row of a gridview the system posts-back using that CommandName and CommandArgument to post the row that is selected, and then set a Session variable as the ID of that posted selected row. The other controls run Async correctly and the button in question is already registered using this on the RowDataBound event.
Dim gvRowSelect As GridViewRow = e.Row
Dim imbSelect As ImageButton = DirectCast(gvRowSelect.FindControl("imbSelect"), ImageButton)
ScriptManager.GetCurrent(Page).RegisterPostBackControl(imbSelect)
I would like to try and get this session on the button command and somehow within the master page, set a label to the current Session. On the imbSelect command the code is:
Dim cellSnapshot As TableCell = gvSnapshots.Rows(e.CommandArgument).Cells(0)
Session("Snapshot") = cellSnapshot.Text
Within the masterpage is there anyway of calling a function after the Page_Load, and after it has resolved all Postback events?

Over the last few weeks i have been trying to add a final level of nodes to my treeview from databases.Within each database is the title of the next node and the key of the node, the child nodes are linked to the parent nodes by the row number/ID column.That is my scenario.
Now comes the next "challenge" At the moment in my code i have had to take out the parts that cycle through each database to add the children as it was causing an error that is described (Learn how to insert hyperlink) here: [URL].. So to overcome that i removed it (dumb approach i know) My justification is that i wanted to see if "my" code worked to add all levels of the nodes. But instead of having All the nodes that should be visible, i only have all the last ones: heres a 'picture to show'What i have below; Whereas all the parents should have children, all the children grandchildren and the grandchildren greatgrandchildren.

View 7 RepliesI'm running three subs in turn (one for each stage of the process that I'm carrying out).The first two of them run a VB Process using:
myProcess.StartInfo.RedirectStandardOutput =

They then use the StandardOutput of their process to update one TextBox that I'm using for the output of all three stages.The final sub uses the shell because I can't get the EXE that I'm running with it to work properly using a process (this is not necessarily the problem though).The problem is that nothing changes in my textBox until the final sub has finished. The first two sub's output doesn't appear even though this should be just a linear process...
