I have a windows form with a textbox bound to a data table and a PDF Viewer both in the same form. I could change the text on the textbox and the Viewer would show whatever is linked to the textbox. I am trying to create a separate form to put the viewer in but at a loss on how to link it to the textbox on the first form.
View 4 RepliesI would like my application to do something (in one form) and while form is doing that i would like to show another form to the user. Code is:
Private Sub blaa()
Dim a As New Working() 'working is another form
a.Show()
'Do some stuff
a.Close()
End Sub
But when i make new form i find it is on the same (main thread) and therefore new form also frozes. How to make new form on separate thread?
I have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?
View 6 RepliesI have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I am using visual studio 2010 to create a VB reporting website. I found a blog which tells me how to use range bar chart to create a gantt chart. But I got some problems with how to group the bars(tasks) on task names.
My database structrue is shown below:
Taskname StartTime EndTime
task1 2012-03-01 8:00 2012-03-01 10:00
task2 2012-03-01 9:00 2012-03-01 14:00
task1 2012-03-01 17:00 2012-03-01 18:00
task2 2012-03-03 18:00 2012-03-03 19:30
I would like use the above data to generate a gantt chart like this:
task1 task1
----- ---
task 2 task 2
------------------------- -------
In visual studio's report designer, I first added a range bar chart. Then dropped the taskname filed to the category fileds. So my understanding is the range bars will be grouped by task name. For the data fields, I dropped starttime(start value) and endtime(top value). I also set the 'draw side by side' property to false. But when I run my website, I could only see one task for each task type in the gantt chart( one task1 and one task 2) . It didn't show me all the tasks. So my incorrect result is shown below:
task1
------
task 2
-------------------------
No matter how many records are there in my database, the gantt chart only shows the first record for each task type.
I have never used table layout, and not sure if it the best way to go.Here is my objective. I need to create a Schedule Viewer, pretty much a table. The columns would be "Station Names", Station1, Station2, etc. And the Rows would be time of day. At the intersect of the row and column would either be OPEN of the time for that station is open, or the last name of the user who has that stationed booked.I have all of this data in my database. I just need to display it. I don't think I can use a traditional datagrid because the columns are data too.
I also need to build this grid programmable, because every client will have a different amount of stations and different times available.
How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :

Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub

I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?

Currently I'm creating a task that runs a hardware i/o loop for the duration of my program.i.e. it's a task that's created at the program's start and runs a loop that is only broken at the programs termination. Each loop cycle communicates via ethernet to hardware.depending on time outs each cycle takes 30-300 msec)I've noticed that if the loop runs with out any break that the program really slows down... to counter act that I placed a thread.sleep(x) in the loop

View 2 RepliesThe company I work for has a VB6 project that is using an ACCESS database.The project consists of seperate modules such as Accounts Payable, Payroll, General Ledger, and Inventory.At the current time each module is a seperate project in VB6 and the EXE files are called when needed.In total there are about 1300 forms in the project.We are moving from ACCESS to Sql Server and from VB6 to VB2008.The question that I (we) have is as follows; Should we continue to keep each module seperate and call the EXE's or should we create one large project?What are the pros and cons for each way?Is there something written that explains the advantages of either?

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.
