I'm at present looking at various ways on how to convert files without any extension and making them with a .txt extension. At present, I'm using the RENAME feature within windows to do this, but i takes time when there are a lot of files to rename. Can anybody give me a few pointers on how this can be done using Visual Basic?
View 3 Repliesmy goal is to
1.Take an file(exe,dll,etc)
2.Convert it into hex
3.place that hex values in a stack
4.Execute the values inside the stack to its original form(i.e. take the elements out of stack and then convert it to a compile format)

I am using VB 08 running an openfiledialogue wanting to get the result of the GDS file (*.gds) to be the default extension at the drop down menu instead of All file when the openfiledialogue box opens.
I coded it with:
OpenFileDialogue.Filter = "GDS File(*.gds)|*.gds|All files|*.*"
but the results i get in the open file dialogue box remains as all files being in the drop down menu as the default file extension. How to i set it to ".gds" format?

View 4 RepliesI have a program that processes files in a special subdirectory and the program processes the files based upon the "Type", i.e., "Text Document". If an application, such as a text editor, installed onto the system, the "Type" may change to suit that application. For example, I recently had one change the type from "TXT File" to "UltraEdit Document (.txt}". Yes, the squirrely brace was on the end, don't know why. Well, after this app was installed, my program found no files of "TXT File" type to process even though the subdirectory was full of filename.txt files.
So, how can I get the code to look at the file extension, not the Type? A few lines of the code are shown:

Here on my local server when I use ffmpeg.exe tool with c# code everything is working good. But when I deploy the same code with ffmpeg tool on to my hosting server, where as .exe files are not allowed to execute, the code is not running. Is there any other way to achieve the same other than redirecting to video conversion sites because I want to save .flv files on my hosting server.

View 2 RepliesWhy would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?
I am trying to convert a VB5 program to VB2010 so that I can continue to support it on my new PC. My copy of VB5 was an upgrade from VB3 which was an upgrade from VB2 which came on floppies, so I can't just install every preceding version as my new PC doesn't have a floppy drive.I have accepted that I will have to design all the forms from scratch (whatever happened to twips?) and will have to go through the thousands of lines of code line-by-line, but I have hit a brick wall when it comes to random access files. One such file is defined in the Declarations section of Module1 thus:[code]....
I soon found I had to change Type to Structure, but then in the declaration of transrec, transtype acquired a wavy blue underline with the error message: "'transrec' cannot expose type 'transtype' in namespace 'Treasurer_2010' through module 'Module1'.So if I can't use the structure in the module in which it is declared, where can I use it?
I'm trying to convert an old Quick BASIC program to VB.Net. There doesn't appear to be any direct replacement for the old file statements. Building a database seems like overkill for my simple needs.

I am having problems with CodeDomProvider. When I compile a code VB, there is not an error. But, if this code has extensions (ex: string().contains(), char().count, char().AsEnumerable, etc.) at the moment that I call these functions, it's returns an exception equal for all these extensions:
'Public Member 'Count' at type 'Char()' not found'
'Public Member 'Contains' at type 'String()' not found'

These are the Assembly that is referenced to the compile, and this is also configurated for run in Framework 4.0.
Dim Param As New Dictionary(Of String, String)
Param.Add("CompilerVersion", "v4.0")
Dim oCodeProvider = CodeDomProvider.CreateProvider("VisualBasic", Param)
This code is inside a string:

Imports System.Xml
Imports System.Data

After I use it for compile my Assembly. The code compiles without errors, but when I call the function 'ProcessarLink', it returns me the exception in 'Contains', or when I call the function 'Personalizar' the errors appears with the 'Count'. This happens with the others extensions too, like AsEnumerable, etc.

View 2 RepliesI have a need to create a Tcl extension that calls a managed .NET DLL/Class Library. Currently, the structure of my application is Tcl > DLL Wrapper (C++ CLR) > .NET Class Library (VB.NET), where ">" represents a function call.
My VB.NET DLL just takes a value and returns it back, keeping it simple for now. In the end, this will do some more advanced stuff that makes use of some .NET functionality.
Public Class TestClass
Public Function TestFunction(ByVal param As Integer) As Integer
Return param
End Function
End Class
My Tcl Extension (C++ CLR) creates an object of the type above
int TestCmd(ClientData data, Tcl_Interp *interp, int objc, Tcl_Obj *CONST objv[])
{
// Check the number of arguments
[code].....
If my VB.NET DLL is in the same directory as my extension DLL, the extension crashes when it instantiates a TestClass object. I've noticed if the VB.NET DLL is relocated to C:Tclin, the extension will find it, and TestCmd can be called just fine. The problem is that this will eventually need to be deployed across a number of PCs, and it's preferred not to mingle my application's files with another application's.

I want more customization then the original VS 2010 set up files. So i decided to code everything. For example, i put all my files in my debug folder into my installer.vb's My.Resources. So i usedSystem.IO.File.WriteAllText ---> to install all my files and the .exe one.Everything was installed it except my Ethup Bolt New Build.exe. It shows up in the folder after installation, but when i click on it, it didnt run at all. (It showed up in the task manger, under process, but it disappeared after like 5secs.) So it didnt
run at all. My question is how do i install my .exe properly. ( I DONT WANT TO USE THE ORIGINAL INSTALLER WITH Visual Studio)
