View 12 Repliesim wanting to add a new feature but am unable to even get started. I'm in a windows form in visual basic .net and basically, I have a combobox with 3 items in the drop down menu. I would like to make it to where the moment one of the items in the combo box are selected, the program recognizes the change of index and automatically calls to the function of my choice.
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 ...

View 1 Replies Dim tabnum As Integer = mycontrol.TabIndex
If My.Forms.Sessions.GroupBox1.Controls(tabnum).Enabled = True Then
mycontrol.ForeColor = Color.Red[code]....
I have checked and double checked the tab order on the controls and run traces with debug. The control found in my.forms. sessions. groupbox1 seldom returns the proper tab. Using a 'watch' I can see the tab names and the tabname (my.forms.sessions. groupbox1. controls (tabnum).name is often the incorrect one.
Just moved from VB.NET to C#.In VB to connect and Event Handler to a Sub we use the Handles clause.From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code:
this.button1.Click += new System.EventHandler(this.button1_Click);
But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class where control resides.
About some coding in visual basic.NET 2005. I was wondering if it was possible for code to be altered automatically if a certain event was triggered. For example; would it be possible for you to alter the following structure, say if a a button was pressed?
The structure is as follows:
Structure ClientDrawings
Public ClientID As String
Public Drawing_1 As String

I have a datagridview which I am populating of a database, scrollbars are disabled to allow for autoresize
I created a Scroll Event that causes me some issues:
1. I can scroll down only
2. To move from one row to the next I need to rotate the mouse-wheel up in between two rows - as if the row index isn't being updated
3. The procedure results in an error : Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Public Sub grdScroll(ByVal sender As Object, ByVal e As ScrollEventArgs)
Dim RowIndex As Integer = grdAccountTypes.CurrentRow.Index + e.NewValue
' grdAccountTypes.CurrentRow.Index = grdAccountTypes.CurrentRow.Index + e.NewValue
grdAccountTypes(0, RowIndex).Selected = True

In a list of timers, how do I determine the index of the item that elapsed without having to iterate the collection as shown below (e.g. can I pass a paramater to OnTimedEvent, or can the collection raise an event to say which item fired???). It's the individual timer index that I need as I'm using it to refer to something else.
(I wont know how many items I'll have in the list in advance so I can't create an individual event handler for each timer - I don't think I should even if I did).
Public Class Form1
Private _timers As New List(Of System.Timers.Timer)
Private Sub Form3_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I am trying to make a reminder, but i can't figure out one thing. Anybody out there knows how? I would like my reminder to have a function when you select one date it automaticaly adds 2 reminders up to the day of the event. For example if you select the event at date 24 it would automatically add two events at the calendar at the dates 17 and 10.
View 3 RepliesI have a list of objects, each with several events. I can add an eventhandler to each object, so I can catch each item's events. But I would also like to know the sender's index in the list (ie, was this object the 3rd, 5th, etc, item in the list?) I'm guessing the object doesn't "know" its position.I could give each object an index number property when it is created and added to the list, so that information could be passed. However, I would have to reindex every item everytime I use remove, insert, etc, methods.
View 4 RepliesI populated a form with several progress bars and added a function to handle a click event via AddHandler. The event fires and I have been able to do things with the control using the passed object 'sender', but I can't for the life of me determine what the index of the control is in the array.
Why is that important to me? Because I want to click the control, have a container of textboxes become visible, and populate them with data from the reference in my database based on what control was clicked, and update that data as needed. Making the container of textboxes visible, and even moving it based on the location of the clicked control in the array are all done and working fine. I just can't seem to get the index of the control.
I need to know what entry (progress bar in this case) was clicked. In the function, I can even do things with a select progress bar using something like pb(x).value = some integer, but I'm trying to find out what 'X" is when the click event fires.
Here are some code snippets...
'Populate page 0 of tab control with progress bars
'TimerCount(int) = number of timer instances active in the database
For x = 0 To TimerCount
[code]....
EDIT: I figured out a work around using the 'name' property, but I would still like to know if what I asked about an index is possible.
How should I go about getting my mouse position over multiple controls, and such. I can't use the form_mouse move event, or any other control event nor can I use them all at the same time cause that would conflict with the actual position I need for an object.
View 10 Repliesis there any control that allows the font to be automatically scaled? example, i want to make the text 80% of the width and height of the control, and it must be centered.
currently im using textrenderer.measurestring repeatedly to determine the largest possible size i could have that would be within 80% of the width and height of the control, and the onpaint handlers graphics.drawstring to keep the text vertically and horizontally centered.

What must i do for the program to control the value of x automatically? that is, suppose i click on btn1, value of x must become 0; if i click on btn2, value of x must become 1 and so on.
I've in my app many self created custom controls (not as a real active x control, but a simple modified class). In this case I'm writing about a groupbox. I've placed many of them on different forms. But now, I want to change the backcolor of this controls. I change the backcolor in the class, rebuild the project, and the backcolor didn't change. Why? I don't want to place the groupbox again, it would be too much work. It should be a chance to do this whithout placing the groupboxes again.
View 1 RepliesI am navigating to a website using a webbrowers control and I wish to automatically scroll the page after it is loaded. I have used scrolltop , scrollleft commands as set out below but nothing seems to happen.
WebBrowser1.Document.Body.ScrollTop = 100

I am using webbrowser control to automatically navigate through facebook.Nothing malicious, just an experiment of sorts.Im working on a bot that that would extract the names of all friends on my friends page, open up those pages, extract their friends names, and repeat.The end result would be a chart of who knows who. A sort of 'six degrees of separation' experiment.I have everything automated up until getting to my friends page and I am having trouble extracting the urls from my friends page. [code] Now, I figure I can extract from <div class=fsl fwb fcb">, but Im confused as to how to go about doing this. On another thread, someone said it cant be done with webbrowser control, but im new automation.
View 11 RepliesI have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?
I want the solution to move to specific control by providing Tab index through coding. Is there any way that i send tab key through coding and cursor move to or focus set to next control?

I'm creating a program in visual basic 2008 that can scan an image straight to a picturebox using a scanner.
View 1 RepliesI'm using this control in a application to load the URL of a .jpg image. The thing is that the image is bigger than the control, so I want it to automatically resize the image, as IE does when the same thing happens there, and it even shows a little magnifier glass to restore the image to full size.How can this be achieved? What happens at default is that the image is bigger than the control, so a quarter of it shows and I have to scroll to see the rest.
