VS 2010 Filesize Is Same As Original After Encryption / Decryption Process
Jun 22, 2011I have (using some examples) created a program which reads from a file, encrypts the content and writes it to a new file. The file can then be reopened in the program and decrypted.Now I am trying to adapt the program to split the file into pieces as specified by the user whilst it is been written to the hard drive. This also works, but when the files are read and decrypted the original file seems to be corrupted. I have been testing it using a JPG which turns out viewable, but is distorted. However the filesize is the same as the orignal after the encryption/decryption process. [code]

Use An Extension Method Instead Of Just Creating Non-extension Sub Or Function?
Dec 3, 2009Why 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?

Anyway To Check Open MS Word Documents Filesize Of Open Document Before Saving Document?
Sep 28, 2011I have a function on my program that allows a user to load a listbox filled with words that are matched with words inside a databank. The databank is filled with 2 string arrays and file of .jpg Pictures. The Arrays attached to each word inside the listbox are approximately one page. Each page is two paragraphs of Text(string Array) and one Picture(20Kbytes).My problem is this. When the user selects the option print all, the listbox with approximately 10255 words is selected and begins to fill a Microsoft Word Document.Because the alotted amount of space needed for the MS Word Document is approximately 5 Gbytes,I need to open about 10 Documents and insert the String Array's and Pictures into each document one at a time.Is there anyway to check the filesize of the Open Document before saving the document.This way I could check the open document inside the algorithm for 512 Mbytes of memory and save the document before the size gets above 512 Mbytes.[code]
View 2 RepliesGetting An Other File Extension As Default Instead Of All Files As Default Extension?
Jun 25, 2009I 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:

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?

.net - Extension And CodeDomProvider
Jul 24, 2011I 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'
Dim refs() As String =
[CODE]...
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
Imports System.Xml
Imports System.Data
[CODE]...
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 RepliesC++ - Tcl Extension Calling A .NET DLL?
Feb 8, 2012I 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.

Extension Of Customize Set Up?
Sep 8, 2011I 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)

VS 2008 : Getting Only The Extension?
Jul 14, 2009I'm making a program where I'm separating the file path and the file extension. The path will be held in one list box and the extension in the other.Right now all I'm trying to to is get the extension since once i have that, i can just take away the extension from the whole string (once i know what it is) and then add that to the other listbox.
VB.NET
With OpenFileDialog1
.FileName = vbNullString
.Multiselect = True
[code]...
The place in that code where I'm trying the get only the extensions is:
"Name_and_Ext.ListBox2.Items.Add(IO.Path.GetExtension(OpenFileDialog1.ToString))"
That code only works if you have one item selected and since my openfiledialog has multiselect enabled, it needs to be able to do however many are selected.
Why Use Extension Methods
Jan 7, 2010I would like to know your opinion on extension methods. Sure, it is a nice feature and makes you feel powerful. It's great to see your own method pop up when typing in a object. But it doesn't really add something new... You can get the job done with normal methods as well. I think extension methods do not belong in object oriented programming. It makes your code easier to read but harder to understand for someone else.

Add-on To Write Shell Extension?
Nov 15, 2011Apparently, it's not safe to use the .Net framework < 4 to write a shell extension.
As my users are likely to not have that version of the framework, I'd rather use a third-party solution so I can write the main app in .Net 2 or 3.
Can someone recommend an add-on for this, either open-source or affordable?
