VS 2008 Loading Executable Into Memory?
Dec 18, 2009
Alright, for a school project i'm making a filecrypter, and i need to load the executable directly into the memory.
For those that don't know it yet, a crypter consists of a crypter, and a seperate "stub"
the crypter crypts the file, and the stub is binded to the file, and upon execution, the stub is executed, and in turn executes the file it's bound to.
I have a RunPE sub, and on itself it works fine
Imports System.Runtime.CompilerServices
Imports System.Reflection
Public Class Form1

In VB 2005, I am calling a C++ DLL function that returns the address in memory and size in bytes of a jpeg image. How can I load that jpeg image directly from memory into a picture box in my VB form? I cannot afford to save it to disk first.

Dim e_magic As Short ' Magic number
Dim e_cblp As Short ' Bytes on last page of file

But Always when it wants to run MoveMemory and move the 64 Bytes(DOS_HEADER) to Memory i get a ArgumentException:The value is outside the expected range.

I have a windows application that dynamically loads DLLs using Reflection.Assembly.LoadFrom(dll_file_name_here).
It works as expected, until I ILMerge the application with another DLL.
So this scenario works fine:
MyApp.exe
MyAppComponent.dll
Plugin.dll
Once I ILMerge MyApp.exe and MyAppComponent.dll resulting in:
MyApp.exe
Plugin.dll
Calling Reflection.Assembly.LoadFrom("Plugin.dll") seems to load successfully, however once I try to do anything with it eg:
foreach ( typeAsm in Reflection.Assembly.LoadFrom("Plugin.dll"))
I get an exception "unable to load one or more of the requested types. retrieve the loader exceptions property for more informtion".
The frustrating thing is I can't really debug it, because debugging pre merging works perfectly!

I'm using the ShockwaveFlash ActiveX control in a VB.NET Windows Forms application and i'm wondering.Is it possible to load an SWF file into the ShockwaveFlash ActiveX object from a memory stream rather then from a file name?
I've noticed that the ActiveX object has such properties as "InlineData" and "MovieData", possibly these could be used.
I've also noticed someone has used Windows Messaging to send a pointer to a stream to the ActiveX control, has anyone seen this done?

I am using the following piece of code to load images as thumbnails to a FlowLayoutPanel control. Unfortunately i get an OutOfMemory exception.As you already guess the memory leak is found at line
Pedit.Image = System.Drawing.Image.FromStream(fs)
So how could i optimize the following code?
Private Sub LoadImagesCommon(ByVal FlowPanel As FlowLayoutPanel, ByVal fi As FileInfo)
Pedit = New DevExpress.XtraEditors.PictureEdit
Pedit.Width = txtIconsWidth.EditValue
[code]....
Update: The problem occurs while loading a number of images (3264x2448px at 300dpi - each image is about 3Mb's)

WebBrowser Example.zip IntroductionBecause the WebBrowser control that we use in .NET is a COM control, not all of its uses are straightforward and some of them (even those which seem like they should be easy) require that we dip into our Interop toolbox in order to properly implement them.
A perfect example of this is loading HTML content into the WebBrowser from memory, rather than a file or a URL. Anyone who's ever used the WebBrowser control before is familiar with the Navigate2 method, which tells the control to load content from a URL (or path to a file). Loading HTML content from memory, however, is a rather elusive practice because of the many steps involved in making it work.
MSHTML.HTMLDocumentYou might notice that the WebBrowser control exposes a "document" property. The object returned by this property can be coerced to the type of "mshtml.HTMLDocument" (you must add a reference to MSHTML to your project in order to make this work) as follows:
Code:Dim clsDocument As mshtml.HTMLDocument = CType(WebBrowser.Document, mshtml.HTMLDocument)
(NOTE: You will have to add a reference to the COM library MSHTML to your project to make this compile)
Once we create an instance of HTMLDocument, a whole new world opens up to us, providing all sorts of DOM access to the content of any given Web page.
If we were to create our own HTMLDocument object from memory, we could use the "write" method to write HTML content to the document from a string variable, like this:
Code:'initialize the document object within the HTMLDocument class... clsDocument.close() clsDocument.open("about:blank")
'write the HTML to the document using the MSHTML "write" method... Dim clsHTML() As Object = {sHTML} m_clsDocument.write(clsHTML) clsHTML= Nothing
WebBrowser Control ImplementationUsing the HTMLDocument returned by the "document" property of the WebBrowser control, however, is not as straight-forward. Because of the way that this object is created and initialized in memory (by the COM WebBrowser control), the "write" method fails when called as above. In order to write content to the HTMLDocument exposed by the WebBrowser control, we must first marshal the string value to a memory space that is compatible with COM. Once the string is properly marshalled, the COM interface IPersistStreamInit (implemented by the HTMLDocument class) must be used to pass the value into the object.
Interop DeclarationsIn order to pull all of this off, we must declare several Interop pieces, including an enumeration, a function, and two interfaces. The declarations for these pieces are as follows:

I cannot use Visual Basic 2008 at all. When I go to "new project" and choose "Windows Form Application" I get this error.I have tried multiple uninstall/reinstall with no result.A microsoft reply to this suggested that I needed: " .NET Framework 2.0 Service Pack 1 " I checked, and I did not have the .netframework 2.0 service Pack 1.
When I tried to download and install the above from Microsoft.com, the istaller said that "it was not allowsed" and I was not able to install the service pack 1.
I tried Uninstalling net framework 3.5, 3.0, 2.0 and then reinstalling .netframework 2.0 sevice pack 1; then reinstalling Visual basic 2008 express edition. At the reinstall of Visual basic 2008, .netframework 2.0 sevice pack 1 is unistalled by .net framework service pack 2.When I check the foruims for simiar problems, the formus are mostly for Visual basic 5.0, or other programs that I do not have.
Here is the programs I have installed:
Operating system: Windows XP
Microsoft .net framework 1.1
Microsoft .NET framwork 1.1 Hotfix(KB928366)
Microsoft .Net Framework 2.0 Service Pack 2

I have a program that outputs a file. I want the user to be able to just double-click the output file and launch the program, just like Word and Excel. In Word for instance, one doesn't necessarily have to open WORD then click on File--> Open and locate another Word doc. He can just go to the folder and open the Word doc. I want to implement the exact scenario in my program.
So far I have tried creating TextFile and added it to the Resources. On FormLoading, I simply I stream-read the Resouce file, but I can't write to the Resource on FormClosing, since the Resource is ReadOnly. Also, the Resource is built & compiled so I suppose you can't add anything to it at run time.How you lunch an output file without launching the Executable program that created it?

I have an executable that I was able to get working on all XP machines by registering all the .dll's associated with it.On Vista, however, I go through the exact same registration process but right when I open the executable it goes to a "WindowsApplication1 has stopped working" dialog. I registered the DLLs in the SysWOW64 folder. I also ran Dependency Walker which came up with IEFrame.dll as flagged, don't know if that is relevant though.

My issue is when I read from an existing executable and convert it to string and back to executable windows says it is not a recognized 32 bit or 64 bit application? The code below is real code I have rewritten many times but to no avail. If I leave out the part where I convert the bytes to string and just copy the binary and create a new exe with the binary the program works. But the whole concept of string converting back to valid binary has me stumped? This is Visual Basic 2008 code:
Imports System.IO
Imports System.Text
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim tempPath = System.IO.Path.GetTempPath

VS sets your project up with the default directory structure: ...indebug which also seems to contain some other files besides your dll (I assume these are related to the debug symbols, etc).So how do you set it up to copy your dll to another directory when debugging?Right now, I'm having to manually copy the built dll with every run and that's getting to be a bit annoying.I'm using VS 2008?

i am trying to open an external executable file during runtime using a process component and the process.start() method. I've been testing out my code with various executable files on my C: drive....some work and some do not work. I've been able to successfully open Adobe Acrobat, Microsoft Excel, and Notepad; however, when I try opening various other executables the following exception gets thrown:
A first chance exception of type 'System.ComponentModel.Win32Exception' occurred in System.dll
I cannot figure out why some programs open just fine while others cause the above exception to be thrown.

What i need exactly is to make a program that have a button called "browse" , when the user clicks it , it prompts the explorer and let the user choose a .exe file, then theres another button called "merge", when the user clicks it, i want the file that was already selected to be merged with one that will be already on my project, and the result would be a single executable file, that will open the 2 .exe files when running it. Obviously i could do all the steps, but im stuck on the file merging part.

I want one of my applications to send an HTML email message to a user with a hyper link in it to start up an executable with arguments passed to it. It works fine if I just specify the executable path with no arguments. But if I pass the arguments then Outlook says it can't find the file. Here is the line that I add to the email message body to start the exe only:

I Actually want to provide a new service which requires creating executables on the fly from executables generated in vb.net. For example lets say I have a form with a textbox and in that textbox we pass an argument which is for example the serial of the product, then we have a button which once clicked will generate an executable on the fly which has also a textbox requiring that serial to run? That was only an example but the main thing is how to generate that exe on the fly.

Im getting a problem with one of my programs I have made in visual basic.NET where it gives me a memory error when i debug the program in the IDE. the exact error is this: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt". My program basically has a few forms with text fields on that get their text values from an access database on the same hard drive. Im wondering if im doing something wrong because my program just seems to eat up memory whenever it does anything. For example I have one form that has a combobox on it and when you change the drop down list selection it retreives a few strings from the database and puts them into the relevant text boxes, if you keep changing the selection then the memory usage (in task manager) just keeps going up and up. occasionally I get the error mentioned above when debugging but in my built version of the program it throws an exception everytime the memory usage gets past 49K.
Also I noticed when debugging in the "immediate window" frame I get the following message often:A first chance exception of type 'System. Invalid OperationException' occurred in System.Data.dll...Do I need to somehow be "releasing" the memory that is used to gather data once it becomes redundant?
