Executing MATLAB Program In .NET?
Dec 24, 2009I am working on a project, in which I have to run a MATLAB program in VB.NET In the project there is a VB.NET GUI, which contains a browse button. The user has to click on the browse button and select an image for processing. The user then has to click on the Process button for processing the image. After clicking the process button the image selected by the user has to go as input to the MATLAB program.
Q1) I want to know how to give the image selected by the browse button of VB.NET, as input to the MATLAB program for processing?Also while the image is being processed in MATLAB, a message such as "The image is being processed" must be displayed on the VB.NET GUI.
Q2) how to display the message "The image is being processed" on the VB.NET GUI, while the image is being processed in MATLAB?After the image has been processed in MATLAB, the image must be displayed on the VB.NET GUI.
Q3)how to display the image from MATLAB program in VB.NET GUI?

View 1 RepliesSend Messages Between Matlab VB6 And .NET Programs?
May 16, 2009We are upgrading a suite of data acquisition and analysis routines from VB6 programs to a mixture of VB.NET, VB6, and Matlab programs. We want to keep the system modular (separate EXEs) so we can easily create specialized stand-alone analysis programs without having to constantly upgrade one massive application. We have used MBInterProcess to send messages between EXEs when all the programs were written in VB6 and this worked perfectly for us (e.g., to have the data acquisition EXE send the latest file name to a stand-alone data display program). Unfortunately, this ActiveX cannot be used within Matlab or VB.NET to receive messages. We are wondering what is the simplest string message passing system (pipes, registered messages, etc) that we could adopt. Right now we are just polling to see if new file was written in a specific folder, which can't be the best solution. Our ideal solution would not require a huge investment in time learning nuances of Windows (we are biologists, not full-time programmers) and would work in both WinXP and 64-bit versions of Windows.
In response to the queries, we have wrapped the entire Matlab session within a VB6 program that has the MBInterProcess ActiveX control. That works but is not a great solution for us since it will probably lock us into WinXP forever (and certainly will prevent us from using the 64-bit version of Matlab). The latest version of Matlab (2009a) can access .NET functions directly, so we assume one solution might be to use the .NET library to implement pipes (or something similar) across programs. We would like to recreate the elegantly simple syntax of the MBInterProcess ActiveX and have a piece of code that listens for a message with that program's top-level Windows name, and then call a specific Matlab m-file, or VB.NET function, with the string data (e.g., file name) as an argument.

View 1 RepliesTransferring A Matlab Function To Visual Basic?
May 10, 2012I am trying to transfer a very complicated Matlab function into visual basic. It takes a matrix input and gives 4 outputs.
From my own research I found something called Matlab CODER, which can transfer matlab code into C/C++ code, however, this function is too complex for that. So I guess now my question is, it is possible to call my matlab function somehow within VB and store the outputs for use within my VB program?
The matlab function looks something like this:
function [f,x,s,c,l] = mytest(Y,varargin)

Plugin Using Matlab COM Automation Server...Error: 'Could Not Load Interop.MLApp'
Apr 26, 2010My Problem: I am using Matlab COM Automation Server to call and execute matlab .m files from a VB.Net plugin for a CAD program called Rhino 3D. The code works flawlessly when set up as a simple Windows Application in Visual Studio, but when I insert it (and make the requisite reference) into my .Net plugin and test it in the CAD program I get the following error: "Could not load file or assembly 'Interop.MLApp, Version 1.0.0.0, culture=neutral, PublicKeyToken=null' or one of its dependencies. the system cannot find the file specified."
What I've Tried: I am baffled as to why this occurs, but I was able to contact the CAD program's technical support staff and they suggested that it has something to do with their DotNet SDK having trouble with references that are located far outside the CAD program directory. They didn't have any solutions so I tried playing around with copylocal and this made no difference. I tried using other COM libraries and the Open Office automation server works fine, although uses url's instead of requiring a reference. I also tested Excel, which does require a reference, and it returned the error: "retrieving the COM class factory for component with CLSID {...} failed due to the following error: 80040154." This may or may not be related to the issue with the Matlab COM reference, but I thought was worthwhile to share. Perhaps is there another way to reference Interop.MLApp?

C# - Open A Read Only File As Non Read Only And Save/overwrite?
Sep 21, 2011I have a number of word documents I am converting. Everything is going great until I get a file that is read only. In this case I get a Save As prompt.
Is there any way to open the file in read/write format? I should have admin privileges so access isn't an issue.
I'm using VB.net to open the files. More specifically
doc = word.Documents.Open(path, Type.Missing, False, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing)

May 4, 2009I 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?
Read XML File - Read The Data From ?

File I/O And Registry :: Open / Read Binary File / Care To Check Code?
Jun 14, 2009I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.

Is there any Windows API Routine to read something like that?Or could you point me an URL where something is implemented?I don't want a procedure to read the file line by line and comparing them with Line Input because blank spaces, empty lines and comments starting with " // " may appear too, and I don't want to take them into account, but also I need to save changes to the file, but only to the modified section, without having to read the whole file, and re-write it completely.
Binary access can't work, because I don't know what's the size of each "section", since the number of elements into it can change.
I need something like the "ReadINI" Windows API Procedure, but allowing me to read the "[XXX]" sections headers, and also the "<XXX>" file title header.

The application is a launcher for a private server for world of warcraft.I have a menu bar that pulls the file path of the wow.exe and puts it in a hidden textbox, I then have another option that saves this text to c:wowexe.txt. All of this works GREAT!
How can I read the .txt file to end and return the information stored in the .txt file to this line of code.

If your wondering why I don't just type in the path of the .exe, it's simple, not everyone installs World of Warcraft on the C drive.
