VS 2010 F8 (stepping)executes Only First DIM Stmt And That's It?
Dec 23, 2010
'global declaration
Dim FILE_NAME As String = "EventList.txt"
Dim PATH_FILE As String = Environment.CurrentDirectory() & "" & FILE_NAME
'end of global declaration
[Code]...
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

I have a VB application that executes an external application, via Shell().
What I want is to be able to have control over the "shortcut properties", if you will (such as icon & title), resulting in the external app being forced to use that specified icon and title for its spot in the taskbar while it is running.
A normal desktop shortcut does this easily (by editing its properties) but I don't know if it's possible to take advantage of that.

I am using VB.net 2003 application program. I am trying to do a select statement whereby I'm searching between 2 datetime values that are being stored as datetime. records are stored inside Access. For example, I am searching between 2 datetime:
StartTime = 2/23/2009 9:00:00 AM
EndTime = 2/23/2009 11:30:00 AM
So I need to find all the records in between 9:00 AM and 11:30 AM on 2/23/2009.
strSQL = "select OrderID from Orders Where OrderDate >= ('" & StartTime & "') AND OrderDate <= ('" & EndTime & "') "
but i got the error showing below:
An unhandled exception of type 'System.Data.OleDb.OleDBException' occurred in system.data.dll
strSQL = "select OrderID from Orders Where OrderDate >= DATEVALUE('" & StartTime & "') AND OrderDate <= DATEVALUE('" & EndTime & "') "
But when I use DATEVALUE, it takes the date from the string and set time as midnight (00:00:00). So it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
strSQL = "select OrderID from Orders Where OrderDate >= TimeValue('" & StartTime & "') AND OrderDate <= TimeValue('" & EndTime & "') "
And when I use TimeValue, it returns the time from the string and set date as jan 1st. so it returns no records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. [Code]
but none of the codes above is returning records between 9:00 AM and 11:30 AM on 2/23/2009, but I can see there are records. i searched and found all those examples. but that didn't work. Is there anyway i can search between 2 datetime values. i need to find all the records that lies between that time period (for example: between 9:00 AM and 11:30 AM on 2/23/2009).

I am trying to export some data from a SQL Express table to Access using VB.net. The data is correctly displayed in SQL as, for example, temperature with the small degree object and the letters F or C for Farenhiet or Celsius. The character is of course represented by ° = "°" in html code, which is what appears in my access tables.
How can I get the insert statements to correctly pass this symbol? I have thousands of records and this applies to maybe a hundred or so in each of a few hundred DB's I am running this conversion on.I read the data from a Gridview an .aspx .net web page and then use an insert query with an Access OLEDB connection.

Is there a way to suppress that? I tried:View, Other Windows, Output and then unchecked step filtering messages and that doesn't seem to work.
I also tried:

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

After 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

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?

I 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?

I 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.

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?

I 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.

I have a vb.net app using plain old ado.net to run a s'proc on the database server. The proc simply inserts a record that contains binary data.When this executes, I can see the exec call on the proc being made from within sql profiler.ado.net claims everything worked, no errors. However, a record isn't inserted. There are no key collisions or anything like that.I copied the query I saw from profiler and ran it directly within management studio. When I run it there, the record is inserted.For whatever reason, sql server and ado.net were conspiring against me. The user account I was attempting to execute the s'proc under did not have execute rights for it. After I set those rights then it was proceeding as normal.Now, the problem I have is that there should have been some type of warning, error, exception, whatever that said "hey, you can't do this" instead of simply saying "Everything is good" But that's a question for Microsoft.

Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object.

im using VS2005. and the built-in sql express.when i run my code in debug mode, i can see that the required number of rows are being affected correctly.but when i actually go and see in the table data, the data has not been inserted/updated.i am using sqlcommand. executeNonQuery() to insert/update data.also, i must add that both executeScalar and executeReader are working perfectly.what could be the possible reason for executeNonQuery although showing the number of rows affected but does not actually do it when seen in the table data?int x = cmd.ExecuteScalar(); // X SHOWS 2 OR 3 depending on the number of rows affected.

I am using Visual Basic 2005. The program I am creating can either bring up a form (with a bunch of buttons, listboxes and a picturebox) and the user can enter file names onto the form OR the user can drag file names from Windows Explorer and drop the names on the program icon to start the program. During the execution of the program, messages are displayed in one of the listboxes.
All this works fine except for part of the drag/drop scenario. When the drag/drop is done, the form is not fully loaded when the code function starts to put out messages. This means the user may not see any of the messages until all is complete. I have tried putting my executable code in the Form1_Shown() and even added a timer to slow things down a little, but nothing seems to work consistently.
