How To Write A Dll With Accpeting Parameters From External Applications
Jun 8, 2011
I would like to know how to write a "Console application" in dll form for a patch installer so that I could call it from the installers and find out the installation of a program.I have created a VB.NET class project and checked the COM Interoperation or sort of on project's property, build section.Now the main thing is on receiving parameters and returning the value. (I try to do this DLL as "all-in-one" DLL because this application is part of a bigger suite family, which means there are few others applications that requires the similar approach, and I want to avoid to re-write a dll for each application, and their respective versions.)
I am using VS 2010 to create a Mac OSX like dock application.Everything has worked great apart from one of the key features of the dock! So what I want is:When the user clicks the minimize but on any (including external application) it minimize to the dock I have created rather than the windows Task-bar.
Whats up all I've recently been working with the MDI options in vb.net but I have a question. Is there away to open external applications inside of the MDI application. What I mean is Taking command prompt for example and opening it withing my MDI app. It only shows the file in my app and not on the taskbar. Can I do it or no?
I am trying to extend some features of a external programm that is not able to use plugins or something. So I have to write my own app that reads the text from a textbox from this external application and trigger some own actions.
By using the FindWindow API in user32.dll I allready catched up the handle for the external application. But now I am kind of stuck. By using Spy++ from the Visual Studio Tools I got the information that the class name from the control I would like to read from is "WindowsForms10.EDIT.app.0.218f99c", but there are several of them. Additionally every time the external app starts it creates a new control id for the textbox I want to read.
I am developing an application which launch an external windows app, ei called APL.exe Also, this APL.exe launch two console utils, ie. named CON1.exe and CON2.exe I would like to know if is there any way, after APL.exe has died, of killing CON1.exe and CON2.exe, because there is a small possibility that they will not died completly after APL.exe has exited.Also there is another requirement. My final app version could be executed twice in the same machine, so there could be two instances of CON1.exe and CON2.exe, and because this I need a way to kill them not by process name, but knowing which of them has been launched by my current application instance.
Trying to emulate a typing application that when typing data in a WPF form, the info gets transferred to another application, such as notepad, word, etc. My first attempt involved using the .Sendkeys method but it doesn't seem to be repeatable 100% of the time. I initially had a button that when pressed would transfer data from a WPF app field to an open notepad app. Again, if I pressed it several times in a row, it would be hit or miss. It's like it hangs up and then after enough time, I try again and it works. I really need it to be 100%. Is there a fix for this method or should I take on a different approach? It would be ideal if I could go from notepad, word, etc. back to the WPF form as well, but I thought I would get one way working first.
Client application: This would query the database for information and then display this information on a map.
Database: holds vehicle information such as speed, location, payload etc.
Database update: This application would need to continually check for information received from vehicles and then add that to the database.
I am confident that with my current skill set and some research and learning, I could write the client application and interface it to a database. However, I am at a loss as to how to write the database updater. Presumably, this would be an application running continually on the server, waiting for information to be received from vehicles and updating the database. Is this something I can do with ASP.NET and Visual Basic? Or would this require a different way of thinking than writing web pages?
I am trying to write a DLL that will take two parameters; a path and the text to write text to said path.
I want to be able to call this function from any other language that can be coded on windows, but nothing happens when I try to use this?
Public Class UTF16TextFile
Public Function UTF16TextFile(ByVal path As String, ByVal text As String) As String Dim fs As New IO.FileStream(path, IO.FileMode.Create) Dim sw As New IO.StreamWriter(fs, System.Text.Encoding.BigEndianUnicode) sw.WriteLine(text) sw.Close() fs.Close() End Function End Class
I'm having difficulty figuring out how to run different programs with my VB program. Using Excel and other MS office programs is easy enough since I just add in the relevant COMs, but I can't for the life of me find out how to run other programs. I promise I spent many hours searching before bothering you kind folks here! I'd think this is a common issue so maybe I haven't been searching for the right thing.how to write code that will control and read data from applications.I know you can do "Process.Start" to open any application, and it looks like there are ways to determine the controls available on an open application, but I can't figure out how to do it. Is this possible? Or do I have to import a .dll file for every program I want to control? Or are both possible?
I am using Visual Basic 2008 Express Edition. Some of the programs I am writing make extensive use of External files (saved games, data, item lists, etc.) I could use an easy way to get these files to ride allong during deployment (cd mostly). adding them to the resources works for some static pictures, but custom structures into lists of info to read and write from are beond that features abilities, same with the settings feature. I have found in other help referance to "MageUI.exe" so is downloading a .net SDK my solution or is there a better trick I can use?
The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.
I am working on a project that is used for key broadcasting. Don't worry nothing illegal, I'm making a multibox application for world of warcraft. However I am having trouble when it comes to launching and manipulating other applications from another.
I'm writing a query to select all records that has any part of parameter. I have one table called Employees. Some people have name like this: John David Clark If the parameter is
[Code]....
I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:
I am getting error [07002] the # binded parameters < the # of parameters makers, i checked both parameters were perfect even though i am getting this error here is my code
I wanted to know if it is possible to Zip a folder without any external dll nor any external references - just with native features.I've been able to Zip files with System.IO.Packaging, but it does not include folders and I cannot tell it to Zip the parent folder.I know there are external dll and so, but I'd like to know if it's possible to make it from a native way.
Basically Commands has Parameters and parameters has functions like Add, AddWithValue, and etc. In all tutorials i've seen, i usually noticed that they are using Add instead of AddWithValue.

since it saves my coding time. So which is better to use? Which is safe to use? Does it improves performance?
is there a way to get the GET parameters and POST parameters in just one function or Collection in ASP.NET? Like using $_REQUEST in PHP? I'm using VB.NET.
Is there a way to, when a parent application is opened up, that at the click of a button, or anything of designated event, that this parent application can open a secondary one?
I have a trouble making this code work. When executed, it just creates a correct (with the correct name) file with the extension .txt but the the actual text inside .

I made a quite big application and wanted to test it out on my other pc but it didn't even start and gave the system.InvalidException error.
I just the build-function to compile my project. It runs fine on the pc where i developed it. It has some dll's in it: mysql-connector, twitterVB and zipforge.
I'm a new programmer and I'm looking for some guides/series, or something like those, that basically walk you through building some sort of application. For example, I used to buy little sets/kits from radioshack that walked you through building a clock, radio, etc., or other little electronics devices. The kits came with all the parts and instructions so you just assembled them. Hence, I'm just looking for something similar to that for vb, minus the components obviously ;-). I like to learn through hands on experience so I'm just looking for some guides that have you build a program and briefly go explain the workings of the code.
is it possible to use same database for both vb.net appplication and asp.net??and if is possible, how can to connect it?now..i'd build vb.net application and asp.net in my laptop...it can connect..but i wonder how to make the database connect for vb.net and asp.net in real..
