I'm just wondering if it is possible to create an vb.net application to compress files, without using a 3rd party app. If yes, can you please point me in the right direction, give me some tips, tutorials or sample code?

View 3 RepliesI am trying to create an interface between a third party application which can make use of C/C++ DLLs, but no interface directly to .NET. What I was hoping to accomplish (not sure if possible though), is create a very basic C++ DLL (not .NET), which the third party application would call directly. This DLL would contain a basic method such as "DoSomething()". Somehow, from my .NET application, I want to "listen" to this DLL and "takeover" the DoSomething() method, and then returning the result back to the DLL, which will in turn return the result back to the calling third party application.
I don't even know if this is possible because I'm sure I would somehow have to get a hold of the memory space of the DLL as initiated by the third party application. Also, it seems that creating a managed DLL does not work, based on feedback from other individuals who have tried this.
I'm trying to create a DLL injector (merely for 3rd party option-toggling), but for some reason this code doesn't work.It will always return "Failed to create thread!"Here are the contents of the (Form1.vb)

I would like to know if its possible for my vb.net app to monitor a 3rd party application that it starts. I'd like it to check every 0.5 seconds to see if the child app has a dialog box visible with a specific text string caption. If it does then I want to close my app but if isn't yet visible, keep looping until it is. I'm asking because the 3rd party app has "no event firing when the application starts to load and then displays the dialog so there is no way for the 3rd party app to report back" to my vb.net app when this is loaded.
This came from the Technical Support from the 3rd party app after I asked if using waitforinputidle() in my app would allow me to detect when their app finishes loading and enters an idle state (sadly not). However they have suggested that it might be possible to monitor their app for a specific dialog caption and then close my app but this is beyond my novice understanding just now. How to go about such a process?
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.

View 4 RepliesI want to have a backup feature which takes about 7 txt files and compresses/packs them into one file. Then if required at a later stage I can unpack all 7 files from the packed file. I do not need any compression as such just to make one file from 7, then 7 from from that one, if you understand what I mean. I have read there are some native libraries in .NET Framework 2.0 called DeflateStream and GZipStream. Can these be used?
View 3 RepliesI'd like to use WinRAR's dll file to compress files in vb.net.Is there any way this can be done? The only one I found was using the unrar.dll to uncompress files. Also, I'd like to know how to implement WinZIP's dlls to compress files as the zipfldr.dll does not achieve very high levels of compression and encryption.

I have a program I made in vb.net express 2008 that used java.utils.zip to compress my work files to a Zip archive that I ran occassionaly to have a backup. I worked fine, but with net framework 4 and vb.net 2010 it doesn't work. So I modified it to use sharpziplib and it works fine if all files on the filter list in the folder are closed, but if I have a file open in OpenOffice writer, my program can't access it and won't create the zip file. The file that usually stays open all the time is my TODO list, that is updated several times a day , so usually gets printed, and updated( adding or deleting entries), without closing it.

View 3 RepliesI am in the process of writing a win forms desktop app in VB.net that employs user data in the form of rich text, stored internally as an object and then serialised to an XML file for persistent storage purposes.
To create the user data (the application's "document" it might be called), I have written a seperate app that tries to be a word processor and then saves the text in my XML format that can then be opened and used in the main app.
Is there a way I can use Word to do this? Perhaps by writing an add-in or template? Just to clarify, the format of the rich text would just be a table, I then need to save this in my XML format, or save the text as my object then serialize it to file.

View 5 RepliesI have a favorites application which makes files corresponding with the favourites, but with the windows filesystem, I cannot create files with the characters: <> /\ : ? * ". This means that I cannot create favorites with HTTP: in them, which kind of ruins the point of having a favorites viewer. How I could convert the http: to another expression and save it, and then when the project loads make it into http: again. I have thought about using Regex to replace the expressions, but I do not know how to do that in a listbox.
Here is my code:

Dim info As IO.FileInfo

how i would make an application that can create exe files.Like i make an app that has the options:
Form name:
Form icon:
Message to display:
and then you click build, and it builds an exe with the options set in the original form as the settings for the new exe.
I am writing a small application that will display some info to my end user. I have another program that the end user will have open while running my appplication. What I am trying to do is have my application launch itself (and maintain positioning if other app location changes) and "tether" itself to the other application.Ideally the top left of my application would attach to the top right of the other application.I have tried for countless hours working with the GetWindowPos API but the values returned are either all zeros or it just doesn't work.I do a Try/Catch to see if the other app is running and I fetch the Handle of the process. This works fine. Then I try to get the positioning of this process and set my .Left property to the returned RECT's .Left property. no dice.This is Visual Basic 2005 ExpressOther application is a PuTTY window that is not a fullscreen app.

I am trying to read text from a 3rd party application. I can create a catalogue of all possible letter variations. I can store every possible character I encounter as a small bmp, or perhaps as an array/matrix of pixel values. For example:
xxxxOOxxxx
xxxxOOxxxx
xxxxOOxxxx
xxxxOOxxxx
xxxxOOxxxx
the letter "I" could be represented in a 10x5 array or matrix as above. Where x represents a wildcard pixel value, but O represents the expected/pre-defined RGB value.
I want to search specific areas of the screen, pixel by pixel where I expect to find the information I'm after. And convert this to usable information. What method gives the best trade-off for simplicity and speed? And how can I implement this method? How do I search for a bmp within a bmp at specific coordinates?
