I am just trying to learn Visual Basic in 2008. I need some help theory about dll and ocx files. I have seen videos tutorials, and in some of them they use some additional files. i.e. MSwinSck.dll, or DVD .dll ect. But lot of these files does not exist in my program, noone is telling about these files and where to install them or how to get them.

I have recently published a simple text editor(just as an exercise). the editor has been published using Microsoft Visual Basic Express. Once the program is installed i wanted to make it a default opener for .txt files, so i clicked openwith ->Choose default program and then i was asked to show the location of the .exe. It seems like the .exe of my installed program doesn't exist. where the .exe is on a windows7 or tell me of another way of makeing that program the default opener.
Here is the link to the publish page: [URL]
I have a routine which run's on a form load event which works perfectly fine.i am using vb.net.
Now i want the routine to run only when the files (".txt") exists in a folder.I need the program to keep watching the folder and execute when it finds any files in it else sleep & then check to see if it has any new files
I have a list of directories that get files added to by other users on my network.I would like a script (triggered by scheduled task) that would detect if there are files in these folders older than 15 minutes, and send me an email. I am able to run Batch/DOS, Python, Perl, or VBS - I have them all installed on the server. As long as they can be triggered from Scheduled task.
Example:
C:UsersFTPJoeSFromCustomer <files dropped here>
C:UsersFTPMarkFromCustomer <files dropped here>
C:UsersFTPRobbieFromCustomer <files dropped here>
C:UsersFTPTammyFromCustomer <files dropped here>

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?
View 4 RepliesI have created an MSI. Before I install it, I look at "C:Program FilesMyApp" and it does not exist. I execute the MSI and look at "C:Program FilesMyAppData Base" and it contains my database with no data in it. I have checked it everyway possible. I open the app and stop it before the Fill dataset and check the connection string, it points to "C:Program FilesMyAppDataBase". I fill the dataset and it contains data from my previous install of the app. The database at "C:Program FilesMyAppDataBase" is empty. I use Windows explorer and check the database it is empty. I check the adapter and the connection string is "C:Program FilesMyAppDataBase". This is an Access database 2007 and the app is VS2008 in VB. It looks as though the installer is setting up a parallel environment somewhere.
View 8 RepliesI 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 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?
Im having kind of trouble looking for this info, but i created a POS program that when i install it, it install under Local SettingsApps2.0labla

Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata
[CODE]...
Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.
Is it possible to build a program through VB that creates a folder in program files folder and behaves like any other usual program?If not, though witch program can i make this?
View 6 RepliesI am attempting to access an SQL (.mdf) file I have created with the Database Explorer utility of Visual Basic. Here is some relevant code from the program:
Imports System.Data.SqlClient
Dim Database01 As SqlConnection = New SqlConnection("Data Source=C:Test01.mdf")
SMUDatabase01.Open()
At this last line of code, I get the following error message:
"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)".
I am using Windows Vista OS and the firewall is turned off.
I suspect the problem might be the settings (such as connection strings) within the app.config file, but if so I am unsure what the correct coding within this file should be to access the file.
I'm making a presentation program. It's a bit like PowerPoint, but less complicated and for a different purpose.
All files used in the presentation (like images, texts and sounds) should be put into a single 'file-package'. This package should later be opened by my program, which should be able to use the files from the package. (Just like PowerPoint creates a single file with all images and sounds included, which can be loaded in PowerPoint on a different computer.)
Actual compression for the file is not really needed. It could be sort of like a tar-file.
