VS 2005 Include A Header And Libraries From VS C++ In Application
Nov 4, 2009I have a software package with a bunch of libraries and header files that I am trying to use in a VB.net application. The software help file states the following: The MIL DVD includes MIL libraries that support the Microsoft Visual C++ .NET 2003/2005/2008 (unmanaged) compiler under Windows Vista/XP. The DVD also includes ActiveMIL ActiveX controls for Microsoft Visual Basic .NET 2003/2005/2008, Microsoft Visual C# .NET 2003/2005/2008, and Microsoft Visual C++ .NET 2003/2005/2008 RAD tools.
To compile a MIL application program, you must include the mil.h header file, in addition to the required standard C include files. After you have compiled your application program, you will have to link it with the appropriate libraries or import libraries for your operating system, compiler, and target board.

View 3 RepliesClass Libraries (.dll's) Referencing Other Class Libraries (.dll's)?
Dec 17, 2010I designed 7 class libraries for 1 project.The project references all 7 libraries.3 of the 7 libraries make references to the other 4 libraries.I thought of just duplicating the code that's referenced in the other 4 libraries, but thats a lot of code.
Example:
PrjctA makes reference to LibA, LibB, LibC, & LibD.If LibA references LibB & LibC also will this fail?

View 2 RepliesAPIs With 'File Download' Dialog?
Jul 13, 2011I am currently working on an application to automate file download(s). My main application is running a query for downloads with embedded browser. When the results are returned they need to be downloaded and saved. This works fine. The last step of the process it to start download and the 'File Download' dialog pops up. I wanted to create another application that would monitor for the 'File Dialog' windows (knowing the main application Process ID I can ensure that I find only the dialogs generated by my application).

Jan 26, 2012I need an API for sendmessage and sendmessagetimeout for my VB .net application. I have searched quite a bit, and everything I find doesn't seem to work: either the message just doesnt seem to be sent, or the message appears to be sent with the msg parameter always 0, and the wparam setting as what I enter for the msg setting. Pinvoke's also always seems to throw an AccessViolationException for I have no idea what reason. I tried playing around with maybe just where I put the variable, but unsurprisingly, there is not a simple logical switch of the variables.I have tried pinvoke's:

View 1 RepliesSwitchParent - App With The SetParent And SetWindowLong APIs
Feb 3, 2011I have consumed a word doc in my app with the SetParent and SetWindowLong APIs. When I close the app I want to leave the word doc open. I have used the SetParent and used IntPtr.Zero(2nd parameter) which kinda works - it just does not have a document border. Would I use the SetWindowLong function - if so what would the parameters be? I have looked at the SetWindowLong function, just not sure about the second and last parameters. What would be the proper way to do this?

View 2 RepliesC# - Organizing .NET P/Invoke Code To Win32 APIs?
Mar 12, 2010I am refactoring a large and complicated code base in .NET that makes heavy use of P/Invoke to Win32 APIs. The structure of the project is not the greatest and I am finding DllImport statements all over the place, very often duplicated for the same function, and also declared in a variety of ways:The import directives and methods are sometimes declared as public, sometimes private, sometimes as static and sometimes as instance methods. My worry is that refactoring may have unintended consequences but this might be unavoidable.
My instict is to organize a static/shared Win32 P/Invoke API class that lists all of these methods and associated constants in one file... EDIT There are over 70 imports to the user32 DLL.(The code base is made up of over 20 projects with a lot of windows message passing and cross-thread calls. It's also a VB.NET project upgraded from VB6 if that makes a difference.)
Can't Find Any Reference Material Online For These APIs
Mar 10, 2012I'm having some problems with some API calls. I'm trying to return device driver information for a given device in device manager so I can access the available information and display it. I'm using a series of API calls which in turn populates a list with device driver objects associated with that device. The API calls fail. The problem is that I can't find any reference material online for these APIs so I can figure out what's wrong. [code]

Writing To Event Log With My.Application.Log.WriteException
Aug 4, 2009I'm handling the Application.UnhandledException event in a WinForms app and need to log exceptions caught there. My app.config is set up to log exceptions to a FileLog and an EventLog.The problem is that when running as a non-admin user, the EventLog cannot be written to because of a SecurityException - I get the message "The source was not found, but some or all event logs could not be searched."I understand why - the user does not have permission to create the EventLog source, but the question is how should this source be created? As I see it, I could either:
1) Create the EventLog source with my installer, as this is running as admin. How to do this?
2) Create from within my app, by somehow elevating permissions? But this would give the UAC prompt on Vista.
What's the best practice for creating a Windows Application EventLog source on a client machine?

Create A Writing Speed Test Application?
Mar 12, 2012I'd like to create a simple application to determine the writing speed. In this application I want to view a line of text (may be more than one line) to the user to write it. And I want to select (higlight) the character the user pressed in my line and to move like a cursor to the next character (or to put underline under the current charater). How can I do that? and what is the object or component i must use to insert the text. Finally, if I want to make it multiple lines how to determine the enter key pressed by the user and how to move the cursor to the next line?

Writing A Small Application That Downloads Some Files Over Ftp?
Jun 28, 2010I'm writing a small application that downloads some files over ftp, the incoming directory is monitored by FileSystemWatcher_Created, on creation I want to extract some text from the file and call another application with the text as parameters the problem I have is the FileSystemWatcher_Created procedure is triggered before the file has finished downloading, I could download it elsewhere and move into the monitored directory but some of the files may be quite large and Im wondering if there is an efficient way of waiting until the file is ready? along the same lines what is the best way to queue the tasks as there can be many files coming it at one time, I've looked at threading but would that be suitable for such a task as there will still be a bottleneck at the application called by FileSystemWatcher_Created ?
heres an outline of what im doing:

Service Writing Log Files With My.Application.Log To Wrong Folder
Nov 5, 2010I have written a VB.NET (2005) service that is using My.Application.Log to write log entries to a FileLogTraceListener. I have configured the Listener in app.config to write the log file to the executable file's directory by using
location="ExecutableDirectory"
When the service runs, it writes log entries just fine, but they are not in the executable file's folder, but rather in Documents and SettingsLocalServiceApplicationData....1.0.0.0mylog.log
Why is the location parameter not being honored?

Windows Application For Reading / Writing To Specific File
Jan 18, 2011What I am trying to do is I have a .dat file that I cannot read but can at the same time. What I mean is I know how to decipher it by hand (alas takes minutes per 6 parts and there are thousands.) I am trying to make an application that can read this and allow me to edit it from my computer. I can open this with a hex program such as hex editor neo. I am currently trying to get it so I can read the file and have it place corresponding parts in to text boxes that I can alter to suit my needs.
I am new to visual basic and know a tiny bit about C++ if you think I would be better off trying in C# I can try that as well I do know some since learning c++. There are 41 parts to each item listed in the file and each one would need to go in its own text box. In hex there are 348 blocks that need to be arranged in corresponding order. Also the beginning of the file has 6 block followed by a code for each item. I need to find a way to put all the correct code in the correct text box and have it make sense.

View 3 RepliesC# - Using Two .NET Libraries With The Same Namespace?
Apr 11, 2009I'm currently maintaining some old code for a company. As it would happen, the current app I'm modifying uses an older version of the in-house library (we'll call this Lib1.dll). They also have a new version of the library called Lib2.dll that improves upon the previous library in many ways.
Unfortunately, Lib2 is not backward compatible with Lib1. What's worse is that they both use the same namespace Product.Common.
How do I use Lib2 and Lib1 in the same project? Right now if I add references to both of them, VS tells me that certain classes are ambiguous (which makes sense, since they using the same namespace).
Basically, I need something like:
Imports Lib1:Product.Common.Class
I'm using VB.NET 1.1.
