I am trying to create a program that renames files to 1 - (however many files are in the folder) and also convert .pngs to .bmps, I had done this but I messed it up a little. I am not that experienced with VB.Net but I am looking to learn so any help would be great. I have tried this myself but as you can see in the code I've gone the wrong way about it.

I 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

View 7 RepliesWhen I build my DLL in the same solution as my application, it works because the DLL can find the BMPs in the project directory. When I publish the application and install it on another machine, it won't run because it can't find the BMPs. How do I embed the BMPs in the DLL so they are available wherever the application is installed?
This worked a couple of VS releases ago. I am trying to update an application that has been working for years. The old executable still runs. If I use the old code, and publish it without changes, the new executable doesn't work. What do I need to do to carry the BMPs inside the DLL instead of having to create a new directory on the target machine to hold the BMPs?
Is there any way to make an avi file from many bmps?

I am trying to retrieve file details from files in the Program Files folder. I receive an error while trying to retrieve file details.
Dim sFileName As String = ("%ProgramFiles%Windows DefenderMSASCui.exe")
Dim Info As FileVersionInfo
Info = FileVersionInfo.GetVersionInfo(sFileName)
Msgbox(Info.ProductName.ToString())
I receive file not found error at 3rd line. But if I change the path from "%ProgramFiles%Windows DefenderMSASCui.exe" to "c:Program FilesWindows DefenderMSASCui.exe" it works fine.
What should I do if I want to retrieve file details from the path which includes a "%" character?
Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?

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.

I need to convert fdf files to pdf in asp.net using vb. I found some code that I'm trying to learn from. What I would like to do is upload the fdf file and then output a pdf to a directory and email it out. The fdf files are coming from a shared linux/php host (using the php fdf functions is all I can do here on this host) that are emailed to a central inbox. I'm going to pick up the files from the inbox and upload them to a win/asp.net box to convert to pdf.The code i found is below.
* Dim pdfFlat As New MemoryStream() * Dim pdfReader As New PdfReader(context.Request.MapPath(pdfFormFileName)) * Dim pdfStamper As New PdfStamper(pdfReader, pdfFlat) * ' bind fields from fdf... * Dim fdfReader As New FdfReader(context.Request.InputStream) * Dim pdfForm As AcroFields = pdfStamper.AcroFields *

I am using Visual Studio 2008 for my programming class. My professor sends us zip files to open and use to complete assigned projects. When I try to open these files, either the solution or some part of the file is missing. And when I open certain files, part of the file will convert, but the .vbproj part of the file will not convert, and the error message says it is "unable to open project file to perform upgrade.
View 5 RepliesIn class i saved my program in with load of other test programs for the same assignment and got everything mixed up i finally figured out what was what and loaded the program in Visual Basic.

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
I have found several open-source/freeware programs that allow you to convert .doc files to .pdf files, but they're all of the application/printer driver variety, with no SDK attached.
I have found several programs that do have an SDK allowing you to convert .doc files to .pdf files, but they're all of the proprietary type, $2,000 a license or thereabouts.
Does anyone know of any clean, inexpensive (preferably free) programmatic solution to my problem, using C# or VB.NET?
