I have two MS Reports with each their own dataset.The first one works but the other does not fill anything in it's table. When I debug the dataset, just before showing the Report, it's fill, and I did the same setup as with the first report.I get no errors og other input.. The table just not show any rows at all. Is their any log files that can tell me something and if so, where can I find them?
View 2 RepliesWell whenever I reference a file I have been doing so using the full C://location/here kinda way, but my next program will be on CD so I need to figure a way to locate files that will be on the CD drive.In other languages I have used, %A_ScriptDir% and then go from there, is there something similar in vb?
View 10 RepliesI will have people send me (a zipped archive of) an entire VB project and when I try to open it, I get a message that "The system cannot find the file specified" for one or more files. I have had them bring their laptop with the project on it, and it runs, but when I search the folder, I only see the files they sent me. Apparently sometimes files get stored (or moved) elsewhere and their system will track the locations, so their computer can find the files??? Really not sure how or why this is happening.Is there any way to have VB report where all the files in a project are actually located? There are so many files and so many folders in even a simple VB.net project that trying to track these down myself is very frustrating.

View 13 RepliesI'm copying over some files to a target directory on a daily basis.Before I move the new files over, I'd like to delete the old files under the target folder, possibly using System.IO.Directory.Delete()But my problem is, the target folder is on a public drive where everybody in the company could access, and I don't want to empty the folder while someone else might be using those files.I'm thinking whether there's a Class that check the status on the files in a specific directory before I come in and delete everything.(I know I would get an IOException if I disregard the status of the files and try to delete them)

In my application I play sound files that are located in a folder on my computer's desktop.
Const sSoundFolder = "C:UsersChrisDesktopSound"
Now that I'm ready to deploy my app, I want to reference all the audio files so others can hear them in the application.
I read how to reference them... but what I don't know:
Do I have to change the above code to some sort of reference folder in my application instead of my desktop?
Does anyone know where i can find a control for creating reports, e.g. in a pdf format?? Or do i have to create my own report on a form and print the form??
View 2 RepliesI am creating reports in Crystal Reports that is integrated within Visual Studio 2008, and I noticed that some of the features are disabled. One is the ability to link tables with a Right Outer Join or Full Outer Join. I also cannot "Show SQL Query" in Crystal Reports. Is this something I can enable or do I have to purchase or upgrade?
View 1 RepliesBasically, I am looking for a method on how to preview reports from a datagrid or it can be from the access database which populates the data to the datagrid (then displays this in the datagridview) in vb.net vs 2010.I believe there are two methods using the ReportViewer or using Crystal Reports, but so far, I have no idea how to get them to work. The first idea would be favourable - using the data from a datagridview (which may of already been sorted, filter etc) and be able to produce a report on that.

Computer.FileSystem.FileExists(Environment.GetFolderPath(ProgramFiles) to get the Program Files directory in my application. The problem is that when running on a 64 bit version of Windows 7, I am getting the Program Files (x86) directory, not the 64 bit directory. As far as I can tell, everything is compiled as 64 bit.This code is actually in a DLL that is accessed during the installation of the program.
Is there any way to get the 64 bit path?
I want to get the last accessed directory path, what code should I use? The directory path I mean is just like when we use OpenFileDialog, default path of it is the last folder we accessed. I've tried to search but get no result.
View 4 RepliesI currently have an application that uses the FileSystemWatcher object and events to monitor activity in a selected folder. this works great for detecting files being copied to or created in the folder, moved or deleted and changed, however, I am trying to determine if a file is accessed (opened) regardless of if it is modified. One of the NotifyFiler options is LastAccess. It appears that this fires an event, however, it always seems to be the Modified event. I would like to be able to keep track of file access and modification separately. I currently store the activity in a listbox and also in a richtextbox where the text color illustrates the type of activity.Does anyone know how to accomplish determination of file Access versus file Modification?I have included some of my FilesystemWatcher code below.
Code:
Private Delegate Sub AddActivityTextDelegate(ByVal sActivityText As String, ByVal cColor As System.Drawing.Color)

Trying to get this for the last couple of days,but can't figure it out.I found a DVD class in vb.net but how can you tell it what Drive it needs to look for and also to a folder on your harddisk?
I found this one DVD.DVDDirectory = "c:dvdmovievideo_ts"but i'm getting all kinds of weird errors, that its not compatible?
Anyone knows how to do this correctly?I'm just trying to get a overview from a DVD that shows all the titles and chapters/ sound etc..
Suppose I have an IEnumerable such as a List(TValue) and I want to keep track of whether this list is being accessed (to prevent issues with, say, adding to the list while it is being iterated over on a different thread); I can always write code such as the following:
Dim List1 As New List(Of Integer)
Dim IteratingList1 As Boolean = False
' ... some code ... '
[Code]....
(I realize this code is very arbitrary, but it illustrates what I'm talking about.)
My question is whether there's a better/cleaner way to perform this check than by manually updating and accessing a Boolean, as above. I feel like there must be, but, to my knowledge, there isn't any IEnumerable class with a built-in "I am being iterated over" method or property. And writing a new class that implements IEnumerable and contains such a property seems like overkill to me.

View 10 RepliesI have a DataGridView that is embedded in a TabPage of a TabControl and the TabControl is embedded in a SplitterPanel of a SplitContainer and the SplitContainer is embedded in a ToolStripContentPanel of a ToolStripContainer which is on a Form. I want to get the name of the form the DataGridView is on, how do I do this?
Note: Sometimes in my application the DataGridView will not be embedded in any control other than the Form. So I would need this code to work no matter what the DataGridView is embedded in. For example, if I send my DataGridView as an argument to a function how can I get the name of the form the DataGridView is located on?
