I would really like to know if there is anyway in which I can package two or more set up files together with my vb.net application; so that after installing the application, it automatically starts installing the other applications from the other set-up files.
View 5 RepliesThis is the code I have right now
pZipFilename = "C:\123\1234.zip"
Using pkgMain As Package = Package.Open(pZipFilename, FileMode.Open, FileAccess.Read)
For Each pkgPart As PackagePart In pkgMain.GetParts()

The problem I'm having is that pkgMain.GetParts() never returns anything even though the .zip file has around 100 items in it.
I was able to create an application in VB.net that talks to a SQL Server CE database.Now i want to deploy this application using the publish feature with clickonce.An issue im having tho is when I install the application on another computer it keeps looking for my sql server on my development pc.

I'm using the System.IO.Packaging namespace to compress a file. I'm getting an error that says 'file contains corrupted data'. So i tried using a txt file with just a few characters, and I got the same error. I read where someone said to make sure you have all streams closed and I checked this and do so I'm not sure what to try now. Here is my code.

I am looking to write a program for work, which is essentially a skills database. However, I need the program to have a locally held database, which does not require a server.

I am trying to compress and uncompress files. I have read that System.IO.Packaging might suit my needs, but I can not find it. I am using VS 2008 professional. Imports System.IO.Packaging at the top of class does not work (it throws an error). I did find system.io.compression. Does this replace packaging? If it does, does it handle .7z and .rar files?

In the code below I've set it to the maximum compression rate, yet winrar is able to create a zip (at maximum compression) that is 2/3 of the size when I make it. Am i doing something wrong?

I'm using the System.IO.Packaging namespace in my VS2005 application. The zip compression works fine for 1 or many files. The unzip though for some reason seems to only unzip one file. Initially I did this in vs2008 at home and it worked fine, but now at work with vs2005 it's only unzipping one of the files. Can you see anything that I might be doing wrong?

I have developed an app and an installer for it and everything works fine. I now feel I should add a bit of obfuscation to the code before it gets released into the wild. VS2010 comes with the CE edition of dotfuscator so I've run it and it produced an .exe in a 'Dotfuscated' folder. Do I just replace all four 'Primary output from. custom actions with the assembly from the Dotfuscator folder or am I missing something?

This function required the following Iports:

I'm developing a very simple program in VB2010 Express that will create folders based on entries in a remote database. I am fully aware that the minimum requirement to run the exe is the latest .net framework, however I have a few added resources to the file, and when I try to run the executable on another computer, it fails to run stating that the resources are missing.
How do i compile my VB code AND the resources together into a stand-alone executable that only requires the .net framework to be installed?I have already tried to google this issue, however every answer I find has nothing to do with my initial question..

I am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
I have File Like "Sample.bak" and when I compress it to be "Sample.zip" I lose the file extension inside the zip file I meann when I open the compressed file I find "Sample" without any extension.
I use this code :
Dim name As String = Path.GetFileName(filePath).Replace(".Bak", "")
Dim source() As Byte = System.IO.File.ReadAllBytes(filePath)
Dim compressed() As Byte = ConvertToByteArray(source)
System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)
Or using this code :
Public Sub cmdCompressFile(ByVal FileName As String)
'Stream object that reads file contents
Dim streamObj As Stream = New StreamReader(FileName).BaseStream

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...

So any clues as to how I always use file to converts name as defa and where the converted file will reside same dir as original file?
