The code below executes when the user enters the number 4 to see hardware information about the computer in question. Included is the function called to access the WMI Namespace's object collection[code]...
have been experimenting with new algorithms for some existing classes, do it by copy and pasting code into newly created classes, adding the references then trying to adapt the unit tests till thy pass.Am stuck in a case where the code in the newly created class makes a call to another class (shared by the newly created class and the existing working class) and the IDE won't allow me to step into the code, showing "external code" on the call stack and mysteriously stopping on a non-breakpointed line in the code it wouldn't step into...a line that immediately precedes an error-generating line which i'm trying to trace and debug. In addition the working existing class makes the same call with no error and the IDE allows normal stepping into it
View 1 RepliesAfter reading through several forums, which suggested that I should add a referenced DLL (whose source cod I have) to solution as an added project, I am unable to step through the code of the referenced DLL that generates an error. I also turned off"Enable just my code" from Tools->Options-> Debugging. However, I am still not able to step into the referenced DLL's code I added the pdb file and the referenced dll to the bin/Debug folder of the original code that I am working on
View 4 RepliesI have a solution which contains among other things a project which is COM callable.
I would like to put some breakpoints into this and step through it but VS tells me "The breakpoint will not currently be hit".
how I can step into a com callable?
Having a bit of a headache with stepping through a program.
I changed the Keyboard to VB6 in Tools > Options with the same result.
He's what happens.
* I put a break point on Line2. The app stops there and so far so good. * I press F8 or F10 or F11 (tried everything) and the app returns an error on line8 instead of stepping to Line3.
The error is obvious, but I want to step through my program 1 at a time.
1: connData.Open()
2: strSQL = "123"
3: strSQL = "123"

I have a program, which is a GUI, that calls a DLL. I have both the program and DLL checked out of VSS. When I run the program (in debug mode so that I can step thru the code), it's erroring out in the DLL. How can I step into the DLL code to see where the error is occurring?
View 4 RepliesI have a VB6 object that is wrapped by a .NET class. As far as I recall it is possible to step through a VB6 object (compiled as a library) by simply running the VB6 library and inserting a breakpoint at the desired location.However this does not appear to be working in my case. I have attempted to recompile the VB6 object and re-reference it in my .NET project but this doesn't appear to have helped. there a way to insert Debugger.Launch() equivalent into a VB6 project?
View 1 RepliesI am using VS 2010 on Win 7 32 bit.I am debugging a VB application (simple Windows form) by stepping through it with F8; however, for some unknown reason it sporadically runs at full speed after I press the F8 key. This can happen at any given location in code and sometimes not at all.

Using F8 to step through all of the code, it gets to this sub, highlites Dim fs and then hit F8 again it just pops up the form, no message boxes - nothing. Other notes: EventList does exist in stated directory.
Any ideas why it wouldn't complete the sub? the first debug line after hit the f8 is: A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll but the file is there
what is the easiest way to step through a string in this manner... I want to have my program look for one keyword and then another.. in otherwords it needs to find "hello56" and THEN find the word "bob" there are so many places the word "bob" is but I need to locate the "bob" thats after "hello56" Hope this example is clear.

Problem: The excutable of the vb program crashes when trying to run but when I step through the program inside of visual studio it runs successfully.
Details: The program performs a winscp.com transfer from a ftp server and then takes the downloaded file and extracts the data from it before sending it to a webpage. The program also decrypts a des3 encrypted file which holds the login details for the sftp server and the webpage.
My Thoughts: I was thinking this could be something to do with the excutable jumping ahead of the slower transfer and decrypt functions thus causing a "file not found" exception to be produced and the program to exit. Lending to this if I slowly (aka spend 10+ seconds stepping through the code) move through the code it works just fine.
As requested Crash Messages:(I capture everything in exceptions and exit properly so no "crash" is reported but the error I get in my logs is as follows:)
1st run with standard test case:Could not find file 'C:UsersAdministratorDesktop..ILC2INFOENC.txt'
2nd run standard case (the file above was not deleted by my cleanup function either as it could not be found)Could not find file 'C:UsersAdministratorDesktop..ILCNETSL10663.csv'
Background:The first file that is found missing is the encrypted login information file while the second file is the winscp.com downloaded csv file.
I've seen this in two different places & can't quite figure it out. I can think of at least two possibilities but don't have a lot of confidence in either.When stepping thru code I encounter the following:
If x = True Then
y = New ContextMenu
Me.ContextMenu = y
[code]....
x is False. The debugger stops on the If & I press F11 to evaluate it. The Debugger then advances to Me.y.MenuItems.Add(z), which is *not* the next statement that should execute. Nor does it appear as if it does execute as, when I press F11 again, the Debugger exits the Sub, as it should. But why highlight it as if it will execute?This is even more confusing in the next example:
If Not Me.FindForm Is Nothing Then
If Not TypeOf Me Is A AndAlso Not TypeOf Me Is B Then
Me.x = "OFF"
End If
[code]....
Me.FindForm is a Form, so it's not Nothing. Me is type A so the 2nd If is False. The Debugger stops on the 1st If, I press F11 & it advances to the 2nd If, as it should. Then I press F11 again & it advances to FatalException in the Catch block. What? Did the attempt to evaluate the TypeOf Me cause an error? It shouldn't, and it doesn't seem as if it did as F11 again exits the Sub rather than stepping into FatalException. So why did it stop there?
My first thought was that the intermediate code got out of step with the displayed source code. I've seen that in other IDE's with interactive debuggers, but usually because those allow you to run the Debugger without re-compiling the code. Not so with VS-so that seems unlikely.My second thought is that it's stopping there because those are the last 'executable' statements in the Sub. But that doesn't really make sense as, in other Subs, it will stop on the End Sub.
I have a data point with a y-value of 1 being plotted, the MS Chart control will use increments of 0.2 on the y-axis. How can I force it to not use a decimal, keeping in mind I will have values of >100 so I can't just force an increment of 1 on the y-axis?
View 1 RepliesI have created a DLL that contains basic functions used in my projects. With the DLL I:Compiled it as a Release Moved the .dll file to another folder Deleted the .pdb files in the binRelease folder When I add the reference of this DLL to my projects and I debug my code, I step through line-by-line and when it comes to a function from my DLL, it actually opens up the source files of my DLL and debugs line-by-line in the DLL source code.
This is REALLY annoying for my purposes and I have tried many things now to disable the debugger stepping into my DLL code. I did a text search in the DLL file and found it stores the path of the project folder.
So far the only thing that's worked is moving/renaming the folder where the DLL project source files are. But everytime I re-build the DLL, once again I would have to move/rename the folder again as it's updated the location of the source.
When I have a directory setup with a subdirectory and both the top directory and sub directory have files in them I get a list of all the files with no directory info. That's OK, but I need to restore them to another location with the same directory structure in place. I'm essentially copying all files in a directory and it's subs to another location. The problem is the sub directory info is not in the files list so everything goes into the main directory. How do I get around this or can I? Here is what I'm using now.
I have a directory, NewProg in Program Files and a sub directory under it called Sub.
files=dir.getfiles("C:Program FilesNewProg",searchoption.alldirectories)
My.Computer.FileSystem.CopyFile("C:Program FilesNewProg" & File.Name, "C:NewProg" & File.Name,True)The Sub directory is not created and even when it is there, it always comes up empty with all it's files copied into the main NewProg.
Is there a built-in method for stepping back through folder paths? Or a better way then what I'm doing? To go back two folder paths I'm doing it like this...

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I understand that this is probably a commonly asked question.But when do classes become useful?? When "stepping through the code" it appears to be run procedurally.I understand the concept of classes but have of yet to find a "usage" of them.If someone could either point me to a good explanation of Why Or When I should use classes instead of modules this would be helpful. I recently developed a login system which stores users details, emails and other information into a database but im struggling to try and turn it into a class based application I use the step into and step through the code when debugging to try and understand how classes are more useful than modules.

I also tried:

I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:
