I am working with VB2008 sp1 and I want to use some of the Windows API calls. I need a copy of header files so that I can set certain constants to their correct values. Do I have to install sdk 6.1 and will this damage the sdk 6.0A that is already installed. I only use VB and I do not have any other language such as C+ or C# installed

i have 2 listviews in which folder and files are loaded. i'm trying to make a function that, when "Copy" button is pressed copies files/ folders between listviews (between folders "ex: from "D:path" to "E:pathsubpath"). the codes of file copy and folder copy both work but not if add the file.exists / folder.exists lines. if i put a msgbox instead of the filecopy/ foldercopy it displays "file exists" or "folder exist" etc. .. but if add the file copy / folder copy line doens't do nothing.

I'm trying to get a progress bar to work while it copies all files in a folder to another. I've gotten the progress bar to show and display the progress, but during the copying process the app stops displaying anything if I click away and won't display anything until it finishes copying everything. It just freezes with a ghost image in the form while it's copying. How do I prevent the app from freezing during the copying process? I can't even minimize it or move the window around. I hope I made sense. Here's my code.
Dim Files = My.Computer.FileSystem.GetFiles(.SelectedPath, FileIO.SearchOption.SearchTopLevelOnly, "*.*")

I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
View 4 RepliesI have a VB.NET project in Visual Studio 2008 that I created a specialized addin for. The addin prompts the user to select a database table, takes a template form class's files, copies them to another directory within the project, and renames the form class within the copied files. It then opens the new form and adds controls to it based on the fields in the database table.
The copying of the template form causes the background compiler to give 'duplicate member' errors, such as "Private Sub InitializeComponents(...) has multiple definitions with identical signatures," even though I renamed the files of the new form and the class name within them. Sometimes these errors go away before the new form is opened, but when they stick around the new form doesn't open correctly, and it throws an error instead. I implemented some code to wait until there are zero errors in the error list before trying to open the new form. This has helped sometimes, but for some reason sometimes the errors don't go away at all until the addin is closed.
How to copy the template form and rename the copy without the background compiler ever noticing duplicate members. If that's not possible, then perhaps someone has an alternative?
Here is my code that copies and renames the template form:
Private Sub CreateDataForm(ByVal tableName As String, ByVal displayName As String) ', ByVal subDataForms As IList(Of Object))
Try
Dim dataFormClassName As String = "frm" & MakeValidName(displayName)
Dim dataFormFileName As String = dataFormClassName & cVBSuffix

I'm trying to parse through a large file which I know contains the raw data for numerous jpg files. I need to start by identifying the location of header for each jpg image and then carve out the image.The header in this case is as follows;
hxFF hxD8 hxFF hxE0 hx00 hx10 hx4A hx46 hx49 hx46
Where should I write the header file - Using System.Configuration and others? When I write it after the Inherit line in the form code (not the HTML one), it gives a redline under it. I want to start making a website.

I'm using the following code to populate a DataGridView with a worksheet. This is working fine, however, I'm unsure how I can get the Text from the page header. (not to be confused with the column header). Later in my code when I am exporting into an existing workbook with a new worksheet, I'm wanting to use the header text as the tab name. The header text being "September 2009" so that when I import/manipulate/export october, the new tab will be "October 2009" etc. [Code]

View 3 RepliesI'm looking for a way to have my code build two copies of itself at once.The program has an "A" and a "B" configuration that need to be compiled as Prog-A.exe and Prog-B.exe every time the code is compiled. I can do this manually, but I assume there's some way to do it in code? What I'd like is to use conditional compilation to have the A configuration compile so that it runs a "setup as A"-type method on load, and the B likewise, and then have it compile both versions each time.

I've a Crystal Report of one page. Only one.
I want to clone that page, so when you print that report, you get 2 copies with the same data.
I know can be done manually, but i want to avoid of setting up the printer and write "Yes!, i want 2 copies of this".
Timelines ->
NOW ->
Use software, generate Crystal, go to in-built crystal viewer print button, write '2' in copies, print.
I WANT ->
Use softwre, generate Crystal, print dialog come up (this is done), you hit 'Enter' and 2 copies will be printed (a.k.a 2 pages which are the sames)
I looked up for sub.reports but i don't want them in the same page.

View 3 RepliesI have an external harddrive and I usually backup my desktop with a cleanup folder which I usually move to the external harddrive.
The problem is: when I search for a file (i.e. example.mp3) I will find multiple copies which are taking up way too much space.
Is there an app or some code that can search for an extension (i.e. .mp3) and if it finds more than one copy of the same file, it can delete the extra file?
The reason I ask is: I have around 1300 different mp3s on my external harddrive and most of them are extra copies of the same mp3. When I search for the extension mp3 and I want to move all of the mp3s to a single folder I am prompted way too many times for overwriting or keeping the same mp3 file.
I need an app that can force the move without prompting and delete the extra copies; so, I am left with only one copy of each.
i.e.
mp3 files on external hard drive for backup:
song.mp3 > in one folder
song.mp3 > in another folder
