I have a program nearly completed that visits a web page, clicks a button, and goes on. My only problem is, I cannot find out to add the document completed event in a loop. Basically, it visits a web page, was the document completes loading, it clicks a button, but I can't find how to make it loop.

View 1 RepliesI've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...

Thread Completed Event Error
View 8 RepliesI am trying to display the progress bar(marque) in a separate form (progressForm) while i do some calculation in background. I know the typical way of doing it is to include the calculation in background worker and show progressForm in main thread. This approach how ever will lead to lot of synch issues in my application hence I am showing the progressForm using progressForm.ShowDialog() inside the background worker process. But I need to trigger the Completed event with in the application to close the form.
View 1 RepliesI know that there is usually a DoDragDrop method that starts a drag and drop operation. And that there are events (such as DragEnter, DragOver, DragDrop, DragLeave) that can be handled on the target side.
Are there any events on the source of the dragdrop that will tell me whether the dragdrop operation was completed, or possibly cancelled?
I use the following code in a Sub called "updateDb" to accept changes back to the Db, etc. in the .CellEndEdit event from a DataGridView:
Try
' Write changes back to actual .mdb file
' Accept changes from DataGridView object

Which is the most appropriate event to handle for this task? Right now I'm calling the updatedDb sub when the .CellEndEdit event triggers and when the .UserAddedRows event triggers.

i wanted that on the form that i am calling in the event :frmSearchOperationCodes I will call txtOperationCode_Keydown event because I wanted that if txtOperationCode_Keydown is executed something will happen upon showing the other form.i have a textboxt, When i encoded a character on the textboxt and the user will press tab or enter automatically a form will be shown with a datagridview showing all items related to the character encoded on the textbox.

Im trying to create a webform that is a representation of a paper questionnaire that has 14 questions with yes/no answers. If an answer is no, then you must provide information as to why in 3 separate textboxes and store the information only when a user clicks no.I also have 4 drop down lists that are chosen before the user answers the first question that also need to be stored with the textboxes, but the ddl's value does not change after the user starts. Right now I have 3 textboxes and a submit button for each of the 14 questions that are hidden until a user hits a "no" button, in which I change the visible property of all of them and the user then types in their reasons and submits the answer. I am currently doing this for each question and i hide/disable the textboxes and button after submitted.
My problem is that for each event on the 14 submit button's is that I'm forced to open & close an sql connection and insert the values. I know there has to be a way to simply this some so that I dont have 14 different groups of the same code. I would also like a way to eliminate having 40 textboxes on a page lol, because the idea was to have a pop up box or something open that would let the user submit it and then return to the question instead of hiding textboxes, but the user has to see all 14 questions at page load so if you got an answer to that one then that might solve my original question.
I have built a customized control inheriting the maskedtextbox in VB.NET. But i face some issues in the calling of events. For eg. if there is control named : Control1 and in the designer file i set the text property of the same to some value (Control1.Text = "test"), then the text change property is called. But i need to call the event only when the text property is changed during the run time (not while initializing in the designer file). Is there anyway to trigger the text change event only when the text property
is changed in files other than the designer one.

I have an ASP.NET 2.0 that contains a dropdown list used to filter records based on a group number. For example, if the dropdown list selectedvalue = 3, only records containing a 3 in the group number column of the table will display. This is working perfectly. However, when the page first displays the default value is 1, and the records from group 1 do NOT display unless I trigger the dropdown list event. I am trying to get the records to display for group 1 when the page first opens to avoid having to use the dropdown when the page loads. The "drop down list control" filters records in a "data list" control.
I am thinking of writing a piece of VB.NET code to automatically call the Drop Down List's SelectIndexChanged event on the page so the user does not have to do it. how do I call that event from the "On Page Load" or, is there a better way to do this?
While studying sample code for vb.net, I put the code in a button click event and need to click the button to see the results. It would be nice to have this code run by adding Button1_Click() to save time but I get an error because of the parameters needed for the Click event.
I get a suggested "Generate Method Stub for Button click event" which is probably a clue to the problem if I had any idea what that means.
I think I have a timing issue. On the trigger of an event I call a function to update a value:
Private Sub t0_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles t0.Click
Input.ppProperty = "blank"
UpdateRecord("Hey", Input.ppProperty)
MsgBox(Input.ppProperty)
End Sub
[Code] .....
Notice the difference, the property does not update until the function is completely finished.
Why?
I'm developing this procedure using a timer object. The thing is the procedure is not in the timer's event procedure but I want it to depend on the timer's interval when executing, it's just not calling the timer procedure. How can u declare objects and use their event procedures in code.
View 2 RepliesI have a question regarding VB.Net and Object-oriented programming.
I have a solution consisting of two projects.
One project is dedicated to the logic of the application, and one is only to show the Winforms form, and to reflect changes made in the logics project. In other words, when an array filled with various attributes residing in the logics project gets changed, then these changes should be reflected on the form (not that strange in theory).
Here comes the - for me - really tricky part:
I have created user controls, and these are residing in the forms project and placed on the aplication's form. When I click on any one of them, their respective onclick sub gets called okey, but how can I send a message to the logics project from their onclick subs? Basically, I'm not sure on what should be private or not, or possibly how to call the other project correctly. In any case, I can't get it to work.
To sum up: What I need is a line of code calling a class in another project, and someone telling me what should be private, static etc.
This is a working example which draws a rectangle on different location every timer_tick and I fully understand now how it's working:
Code:
Dim i, timercount As Integer
Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint
[code]....
Now I'm looking for a way to draw this rectangles without refreshing them every single tick. I've just started using Visual Basic and I really don't know how to call/raise PictureBox1_Paint event every timer_tick or how to store drawing data in member variables?

View 6 Repliesi'm trying to learn about user controls. I created a user control that has a textbox and a button. What i'd like to be able to do is when i click the button in the user control, populate a label in the aspx page. I understand that i could just have a button on the page that uses some properties on the user control to get that information.. but i'd like to know how to do it with the button the user control.. the reason for this is the button is just an example.. a learning tool. if i can get this working, i'd likely be putting thing in the user control that might require this kind of passing information. Anyway.. i've found some c# examples that i tried to get working as vb.. but once started getting into the delegates and events..
