I have a form with a tab control, now on many of these tabs there is only one control, a mtb, or tb or cbo. When I select the tab and it is the active tab, what event is it so I can select the control?
IE:
me.tabcontrol1. active tab what is this event?
me.mtbcontrol.select
I have read this many times. Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms. What exactly is the difference?

Here's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.
I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.
I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:
The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.
I'm working on a function that handles events from a number of buttons and trying to define a Select...Case based on the clicked button. Something like this...
Private Sub btnClick(ByVal sender As System.Object, ByVal e As System.EventArgs) _ Handles btnThis.Click, _ btnThat.Click, _
[Code]....
which don't work either. Is there any way I can define a Select...Case in this manner or is it always destined to fail due to the attempt at comparison of reference types?
Can a listview multiselect in the same way as a listbox can, when it is set to electionMode = multiSimple?for instance when the listbox is set to selectionMode = multiSimpleyou can just select any number of items in the listbut...with a listview you can only multi-select when you hold down Ctrl. As soon as you lift the Ctrl key and click on an item it de-selects everything and only selects the last one you selected
(In VS 2008) I have a usercontrol that is in the properties list in Design view, but I can not see the actual control, and it creates some error. How can I remove it when I can't select it?
The code below selects all items in a listview control,fine,but I was wondering how I could code to select all but the very last line in the array.[code]
All my controls for getting data from user are in TableLayoutPanels and GroupBoxes inside TableLayoutPanel, I want to set default selected index of entire CoboBoxes to 0 in all TableLayoutPanelsand and GroupBoxes inside TableLayoutPanel. [code]...
I'm wanting to randomize the selection of a select box on a webpage via the webbrowser control.
What I can do.
Dim testRandom As String = curElement.InnerText Dim RandomSplit() As String = Split(testRandom, " ") Dim intRandom As Integer = RandomSplit.Length Dim curRandom As String = curElement.GetAttribute("Value") Dim rnd As Integer, randomNum As New Random
I want to select either "Wave" or "What U Hear" or "Microphone" or "Analog Mix" (LineIn) in the Windows Recording Control applet, i.e. as if I clicked the applicable "Select" checkbox.
I got this VB6 code on the Net (not sure where) and tried to convert it to VB2008. It is very near to correct I think, but the last part does not work.
Why I right click on a node in my treeview the focus moves to this node and then immediately back to the previously selected node. Is there some way that I can allow the right click to select the node?
I am using a treeview to display projects, tasks, time entries, and the people who are working on a project. I would like to allow the user to define a custom grouping (ie. Project->Task->Time Entries or Project->Date (of time entry)->Task->TimeEntry).The relevant groups would be Project, Task, Time Entry, and Person, with some metadata from them. I want to have some modular way to allow a user to specify how they would like to display the information. Does anyone know of a good method by which this can be done? I currently have hard-coded a display which looks like this:
I want to select a node and make another control visible for that node using an if then statement. From what I read I think I have to put the code in the After_Select method. I gave each node its unique name and unique tag but can't figure out how to address a node name. basically want to click a node and make a panel visible associated with that node. tried something like "If me.treeview1.selectednode.nodePanel1 then pnl1.visible=true" but intelisense doesn't recognize any of the named nodes. can anyone give me some sample code.
been a long time since i came to the forum. i use to program a lot in vb6 but its been a long time since i did it so im really rusty. now that im trying to get back to programming, im finding it a bit of a challenge in vb2008... i have this question, im using a datetimepicker control to select dates in a calendar. what im trying to do is disable the textbox in the datetimepicker so that the user can only use the drop down calendar to select the date and not enter the date manually! does any one knows how to disable the textbox in the datetimepicker but still be able to select a date from the calendar???
I have a form where I have to use control arrays to create a multiple input form i.e. rather than processing one transaction at a time up to 16 transactions must be processed. The following really havent given me much problems at this moment labels and textboxes. I use a for construct to create all the controls including a combobox. This is where my question comes in this form combobox has to be linked to a table in a database. But furthermore and this is where it gets complicated for me anyway each seperate combobox must move independly if i select row 5 in the table in combobox 4 combobox 5 which is havent touched should still be on row 1. How do I accomplish this. I'm using a webservice. I have tried passing a loaded dataset . The code that loaded the dataset is as follows
Dim DSInfo As New Project1.localhost4.AccInfo DSInfo.Credentials = System.Net.CredentialCache.DefaultCredentials InformationData.Merge(DSInfo.GetBusinessJournals)
[Code].....
this code doesnt however provide a link to the table equallly creating a dataset in the combobox method ,loading it and then setting it as datasource also provides no link. I know i'm missing something.
I am trying to make a form that can be used to allow users select file(s) from one control and drag them to another. I am stuck. I have done a bunch of research and now have a form that allows the user to select a directory and display the files in a listbox. It works intermittently. The select directory window works when I click the Browse button and it reports that it found a number of files. But they are not in the listbox. When I walk thought the code in DeBug the files are listed.
How to select one cell and mulitple cells in a table using the webbrowser control. E.g. If the web page (local) that I'm viewing in the webbrowser control has tables present in it. When I click on a cell in the table I want to be able to edit the attributes of the cell like adding an align or a class attribute. I think this is possible without using mshtml which I'm trying to avoid as I can't find much user friendly documentation on it.
The text in the webbrowsercontrol is loaded with the foll: WebBrowser1.DocumentText = Form1.RichTextBox1.Text So I am guessing that I need to be able to detect when a cell is selected (<td></td> tag etc) or clicked on and then from that point I can edit the attributes of that specific cell (<td class="jimmy"></td> tag etc).
I'm Using MonthCalendar Control in my Form to select Multiple Dates. (for eg. 1st April,20th April,25th April). I'm planning to Change the date the user clicked by making it BOLD during run time, so that i can retrieve the results in a Date array. [code] MessageBox clearly shows the date selected, but no effect for the "addboldeddate'.
I can't seem to get this to work so I need a fresh set of eyes on it! I have a combobox dropdown with some names. When I select a certain name from the list, I want it to change the textbox property.I tried :if combobox1.selecteditem= "edward" thentextbox1.maxlength= "2"
I am facing an important problem with the LineShape control (installed with the Visual Basic Power Pack) . The problem is that in design time once I have "Sent to back" some controls (other controls, like text boxes), I can no longer select them! The controls get stuck on the form and I can't select them anymore! Even if I select those controls from the Properties window, I still can't do anything with them (like move them over the form etc). Right now I am using VS 2008. However maybe this problems doesn't appear on VS 2010?
I created a Windows Form application that used a Webrowser control to automate the process of entering data into a website. One of the tasks included selecting a server name from a dropdown menu (SELECT tag). I was able to get a collection of all of the OPTION tags and use HTMLElement.SetAttribute("selectedIndex","indexVal ue") to select the server I needed.The website recently went through a redesign and now there are no OPTION tags. It appears that the values for the SELECT tags are added by JavaScript dynamically. I have tried using HTMLElement.SetAttribute("selectedIndex","indexVal ue") directly, but I am unable to select what I need.

I wrote a VB.Net application that displays HTML help files according to user's search results.A user types some keywords and receives a list of HTML help files containing these keywords.When a list item is selected the HTML file is displayed in WebBrowser control.The problem is that I cannot mark the keywords in the displayed HTML file. I need to highlight them like in a standard Help. I tried many options and nothing works.If I change HTML element style manually (background color for a specific string) all pictures attached to this page are not displayed. After "Refresh" operation the pictures are displayed but the text selection is not enabled.I hope there is a standard function for this operation but I cannot find it.
