he lack of VB terminology in the following question - this is all fairly new to me. Anyway, on to my question.I have 2 seperate applications running and they both need to access the same array. Is it possible? If so, how?
View 2 RepliesI didn't know where to post this question so I hope I put it in the right forum...I am not new to Visual Basic, however I am definitely not an advanced user. I would like to build an application that would allow me to interact with other programs on my computer. For example, if I were to build an application that could control iTunes, how would I go about this?
Or, I am looking to make an application that would allow me to do little things on my computer like disable my track pad if I have a mouse plugged in. How would I build something that could interact with windows (or iTunes) like that?
we know that vb using windows messages for raising events etc.. so if we move mouse cursor windows sends mousemove message to our application (WM...) or something like that. my question is: can we send windows messages to an application? i know usage of sendmessage api but its not working. im simply wanna send wmkeydown message to notepad and notepad should get message and write it to the text area right? am i wrong? i tried several ways but didnt worked.
View 2 RepliesI migrated some applications from Visual Studio 2005 to Visual Studio 2010. I develope using VB.NET in VISUAL STUDIO 2010 on a Windows 7 PC (32 bit). The applications writed in VB.NET - VS2005 run correctly in PC having XP, VISTA, WINDOWS 7 and Windows Server 2008. After the migration, the exe of these applications work correctly in PC having XP, Vista, Windows 7 but work stop immediatly on Windows Server 2008. The error returned is 'System.InvalidOperationException'. Seems that the application stop when attempt to evaluate the first global variable that meets. If i change the framework from 2.0 to 3.5, things don't change.

View 4 RepliesI use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).
I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code:
Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1
AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID
Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.
How can I make a report that contains for every record key 3 different layouts for the detail lines
e.g. title activity
Local organization
Loc. Budget Overhead
Accepted Date
Date req.
Date act.

View 1 RepliesI have created an application that will run several other Engineering applications from within it.
I have my main form which will have a button on it for each application that has to be run. All the other projects are complete and have their respective '.EXE' files, which I have added to the main project.
I have coded one of the buttons to start an application, this is as follows;
Private Sub btnCoordsCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCoordsCalc.Click
Process.Start(My.Computer.FileSystem.CurrentDirectory & "Hole_Coordinates_Calculator.exe")
End Sub
This method works OK and does start the application. So my question is; Is this the correct way to do it, or should I import the whole project into my main project?
i am a casual user of visual basic express 2008 and use Vista Home Edition Ive been using it for a while now, with no problems at all. Recently i started to take a look a WPF in my apps, again no problems.(visual basic express ran fine, debugging ran fine & finished apps ran fine)
However for some reason (and all of a sudden) i keep getting errors and none of my apps will start up.
The errors are:vshost.exe has stopped working (I get this when visual basic express starts)PresentationFontCache.exe has stopped working (I get this when visual basic express starts a wpf app)
(Application Name) has stopped working (I get this when running finnished apps)I've tried all the usual methods (Reninstalled VBE & .Net3.5)I cant see why it has stopped working all of a sudden?
I have created a main application form that has buttons that start up various other applications.
Following advice on here from a previous post, I have imported all the files of each separate application into the main application.
There will be times when the user wants to run more than one of these applications at the same time. I know you can just import the '.EXE' file of each app, and you can then run several at a time. But because I have all the files without the .EXE, you can only run one at a time, you have to close one app to start another.
My question is simply; Do I have to import the .EXE file of each app, or is there some code I could put in my main form that will allow me to run more than one app at a time? (the reason for having all the files of each app is so you can make any alterations without having to open each app separately).
The code below is a typical code for one of the applications start buttons, all the buttons codes are the same, apart from the app name, the buttons are imported, so not standard buttons.
Private Sub btnCoordsCalc_ClickButtonArea(ByVal Sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles btnCoordsCalc.ClickButtonArea
Dim frm As New frmHoleCoordinateCalculator

I have created a simple windows forms application. I would like to be able to connect to that running application and view certain properties from a seperate windows form application. In VB6 I would have run the first application and then called GetObject to connect to the instance. Does anybody know how I could do this in .Net. I'm guessing I'd have to use reflection to get a list of applications running and then somehow connect to them but I'm not sure how to do this?
