View 2 RepliesIs it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I am working on an application which will be used to read/write/provide custom functionality using an mdb file. I have been able to create the program, and access my test mdb file just fine using the normal ado connection protocols. The final product will be used in an application/file format where each user will have thier own mdb file, and multiple users will be using the same application on the same computer to access their files. I need to figure out how to load the mdb file at runtime using both an open file dialog, and to be able to double-click the file in windows and have the applicaiton open and load the db that way (I know how to create file associaitons, it is just the databinding that I am having issues with- and the mdb file uses it's own filetype, so I won't step on the toes of MSACCESS).
View 8 RepliesI'm working with a 3rd party assembly to implement something in our in-house software. I can make the refence and work with the library without a problem, but when I run the program to test it i'm getting this error "Can't load file or assembly "assembly file" nor either of its dependencies. The system couldn't find the specified file" (i'm from Mexico, exception is in Spanish so i had to tanslate it, sorry for the poor translation) I have given read and write permission to the file, the folder, and for all users and still wont load it. I saw that the assembly has the PublicKeyToken=null, does that have any to do with that i cant load the assembly?
View 3 RepliesI am creating a test project using IBM's Rational Functional Tester(RFT) tool(we are using the VB version of it and it only supports till .net 3.5).In this project I am making all database queries using the entity framework.The problem is entity framework retrieves "Metadata", "Connection String" etc from the App.Config file,and RFT won't let me add a App.Config to the project(I guess it is designed that way -- I googled adding an App.Config file to an rft project and came up with nothing), and the Entity Framework requires you to have the app.config file at the entry point.I was building the string to pass to entity framework in code, but my boss really does not like that. So looking at my options I think any of the below 2 solutions should suffice
Is their any way to load an App.Config during run-time. Is their any way to add an App.Config to an RFT project(should really be my first question).

I am working on a project where I have to load assemblies (lets call them tasks) at runtime, run the task and then be able to kill off the whole assembly so that the dll can be replaced without interrupting the main application.There are many of these tasks running within the main application,some run sequentially and some run in parallel.Occasionally one or to of these tasks need to be updated and then re-added to the queue. Currently we are stopping the entire application and interrupting the other tasks at whatever stage they are at, which is not ideal.I have figured out that I will have to load each assembly into a separate AppDomain, but loading the assemblies in those domains is proving difficult, especially when I need to actually run the tasks and receive events from them.I have been looking into this problem for a couple of days and have still not managed to get a working proof-of-concept.
I have an Interface for the tasks which includes a 'run' and 'kill' method (subs) and a 'taskstep','complete' and 'killed' event.'taskstep' returns an object to be cached later, 'complete' fires when the whole task is done and 'killed' fires when it is ready to be unloaded.There should also be a timeout on the whole process of two hours and a timeout of 2 minutes on the killed event in case it gets stuck, at which point I would like to be able to unload it, forcing any threads to terminate (which is what 'kill' should do anyway).Each assembly may contain several tasks, all of which should loadable be unloadable.I have no problems loading these tasks as 'plugins' but am lost when trying to both use them and unload them. If I have to create some elaborate wrapper then so be it but is what I need even possible? I have tried inheriting from MarshalByRefObject but I do not even know the assembly fullname unless I load it first, which then locks the file. I have tried loading from a byte array of the assembly. This means that the file is not locked but a copy of it remains in the current appdomain. This will become problematic over the following months / years![code]
I apologize if this is a rudimentry question, but I have an application that makes several calls to several .dll's. I notice that the first time the function is called, it seems to take a very long time (about 10 seconds) for the functions to complete.
View 2 RepliesI have VC++ windows service running on a windows 2008 server which invokes a VB.NET exe with certain comandline parameters using CreateProcess(). VB.NET application has a form wich uses WithEvents to handle certain event. These event handlers are set in the Forms Load event. Problem here is when i debug the VB.NET application individually the application works fine, Forms Load event is getting fired. But when the exe is invoked via the windows service the form Load event does not get fired. Note the Forms Show function called and not showdialogue.
Why this was done i am not sure it was a VB 6.0 code which i have converted to VB.NET. But everything works fine when i debug the application individually on windows 2008 64 bit.
I wrote an assembly(not managed completely ("1.dll"))
i want to load it at runtime (in a managed assembly) but when i try to load it it give me this error:

Not sure if this is the correct place for this postWhat I am trying to do is update dll's in my application.Using VB with dotnet 2 (Visual Studio 2010)The Project has a number of Dll's one of each department i.e. Sales is sales.dll... Development is development.dll etc....Each dll has classes/User controls which is used and dispose depending on the section within the application.Once work has been completed with a dll, it put in the deployment area, currently another is program launching checks the file verison and updates as required, before the main application lauches, this works. The exe hasn't needed updated for a long time as all the changes are in the dlls.
What i have been looking at is update method for the dll's dymanically, when not in use, when the dll called into use or disposed of.I have looking at LoadLibrary/FreeLibrary and application.domain. I have been reading loads and tried out some of the examples, with a modified to suit. I am just not getting it.
I am having another issue with WMP in VB.NET 2010.I wrote an app using WMP in VB.NET 2010, using .NET Framework 4.0 of course, but had to change the framework target to 3.5. After doing this, the WMP component does not work. How, if I even can, fix this problem so that the program will run on .NET Framework 3.5? The error says that it could not load AxInterop.WMPLib.dll because it was built in a runtime newer than the currently loaded one.

I'm creating an app to manage the movies I've watched and get some info about these movies and then display these info in labels.At moment I'm trying to load the "runtime" and "genre" into label3 (runtime) and label5 (genre). Once the movie name is clicked in the listbox control, these info are loaded from a website (webbrowser control) and then displayed in the labels.

I am new to VB. Started making a software. What I want is when a user click in PictureBox he should be able to create a textbox (Read Only) at X, Y coordiantes of picture box. I am able to get X,Y coordinates but dont know how should I create a textbox there during runtime. Also there is another textbox whose text is to be displayed in new textbox in picturebox. I also want to check that if user have entered a comma (,) after string or not in the text.
(eg : "String %d %d",argument 1,argument 2)
Here is code I have created till now : [URL]
The textbox that I create in vb.net does not let me select all the text using the common keystroke control + a at runtime. The textbox is able to detect all other keystroke combinations at runtime, such as control + c, control + v for cut and paste, but it does nothing for when the keystroke control + a is pressed. Is this something that vb.net textboxes do not detect and therefore I would have to program manually by having the program detect keystrokes and then have the program select the text using the code TextBox1.SelectAll() ?

I have a form, with lables and textboxes added at runtime. The labels and textboxes are added properly on form load and display as expected. The form allows tabing into each of the textboxes, but the textbox does not allow user input.
Is this a problem with the way I show the form to the user? >> this particular form is called (frmname.show) from a different form -- If I test this form directly, without being called from a different form, it allows user input in the textboxes. Is it because of the properties I used to create the textbox? >> properties used were - .name, .size, .location, .tag
