I need to extend the functionality of the ToolTip control...Problem: I need to show some introductionary instructions to my users the first time they see a new form based feature in my app. Something along the lines of: '...Welcome to the blah, blah, blah feature. To do this, click that, mouse here, press that so on and so forth...'
Then I want a 'Don't show this again' check box somewhere near the bottom so the 'welcome screen' can be supressed. Currently I'm thinking of loading an app wide form (Public Dim frmMyToolTip as frmToolTip) and using it's .TopMost property to ensure that when I show it, it appears over my modal form (I can Hide/Show at will.) Also without a caption or border, my users can't move it.
As it will be displayed on top of a Modal form, I need a Background worker component to run a timer which will hide the form after a set period. I can store the state of the CheckBox to stop the form from showing next time if user does not require it.
The maximum value that works for AutoPopDelay property of ToolTip is 30 seconds (30000 milliseconds). Any values greater than this maximum will be defaulted to 5 seconds (5000 milliseconds).[url]...
How to set to extend the duration show time for ToolTip? or alway show until the mouse leave the control?
I insert DataGridViewComboBoxColumn columns in a DataViewGrid. That works fine.
Now, I want the user to be able to not only select one list item, but to "drilldown" into the list that is behind the combobox, allowing him to edit (insert/delete/update) the list.
I think it would be a good idea to display a ".." button right behind the dropdown button of the combobox. Pushing it leads to a dialog where the list can be maintained.
What I am stumbling upon is:
How would I create such a custom combobox? Is ComboBox (which is the base for the combo box that the combo box column creates as its edit control) open enough to accommodate such an additional button? What would be the container of the tiny buttoon -- the ComboBox descendant? How I would make the grid create and handle such a custom combobox?
I currently try to solve this by subclassing DataGridViewComboBoxColum, using a DataGridViewComboBoxCell descendent in its CellTemplate assignment, and overriding PositionWEditingPanel and PositionEditingControl to manipulate the sizes of the panel and the combobox so I'd have space for the tiny button. Is that the correct way?
Or would I have to create a DataGridViewColumn descendant which creates a Panel containing a DataGridView combobox edit control and the tiny button? How would I make sure the column keeps care of the combo box so it has the correct items etc?
I'm trying to find a way to reproduce the FolderBrowserDialog control functionality but not in a dialog. I'm been looking around for a good part of today for solutions but with very little progress. I found a few writeups on listing folders and their contents in a treeView but nothing about listing everything including "My Computer", "Desktop", etc. This seems like something that would've been built right in to Visual Studio. I'm working with VS 2005.
I want to create a User-Control that inherits the functionality of a TabContol.
I begin by starting a new project of the type Windows Form Control Library. Next I place a TabControl on the UserControl designer surface and Dock the TabContol to Fill the UserControl.
I go to the code editor for the UserControl and enter the following line of code.
Inherits System.Windows.Form.TabControl
Then I run the program and get an error. Intellisence recommends that I use one of two recomendation. When I accept the recommendation I and try to run the program the problems esculate.
The design-surface is no longer accessable.
I try to comment out the problem lines of code in the UserControl1.Designer.VB file but that doesn't help.
How can I create a UserControl that Inherits the Properties of the TabControl so that the properties of the TabControl are visable in the Properties Window?
I have an application with as many as 625 Textboxes in a runtime generated control array.I add textboxes one at a time in a subroutine.The application ran with no problems until the parameters required more than 256 textboxes at which point it slowed drastically as textboxes were added. At circa 400 Textboxes it died with an out-of-memory condiiton.
The system has 8GB & a 64Bit version of Windows 7.It looks like the tooltips are eating up memory, causing excessive use of virtual memory from Hard Disk & finally causing out-of-memory.I am now running the application with a label which flashes when the mouse hovers. This uses the Handler for MouseHover.Is it possible to get a single Tooltip to function for all the Controls in an Array? I would prefer this to using the Event Handler.
I have searched the web and not found a good resolution for this problem in vb.net. When you change a color in the controls property it does not respond with the color changes.
I am trying some Uiculture change functionality. In that I need the name and text of controls in a form to change the culture. I got some Demo project and it is in C#. I tried to make the same functionality with the C#.net and Also using VB.net. But the below mentioned code returns control name with an underscore as prefix. But I don't want underscore. Code is actually written in Class library. It works perfectly in C#.
Code is written below Dim fields As FieldInfo() = form.[GetType]().GetFields(BindingFlags.Instance Or BindingFlags.DeclaredOnly Or BindingFlags.NonPublic)
I have this flexgrid which shows a different tooltip for every cell it contains. Now I would like to see this exact same tooltip for every cell when I put the flexgrid on enabled = false but I can't find a way to do this.
I would like to set the tool tip of a button on a ToolTip control , but I would like it to do it by code during run time , not during design time . Is it possible ?
Does anyone know if it's possible to skin the tooltip window so it looks like: Attachment 2448.Instead of the yellow box or the balloon like it does now?
I have IE 8 installed on my machine; and trying to integrate the "Caret Browsing" (navigation using Keyboard) concept into application which i am planning to develop.My sample application in VB.NET as follows:Form - Form1Text box - TextBox1A Button - Button1A WebBrowser control - WebBrowser1Added following line of code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click WebBrowser1.Navigate(TextBox1.Text.Trim())
I have a couple of bits of code I add to a textbox in my codebehind on form.If I wanted to extend this class or somehow create a shared instance of this code so I can pass in the parameters for text to display in textbox and use in any of my forms.. [code]
Since you are repeating same operation three times it is best to make a function for it.
CODE:
labels 1-6 are randomly generated numbers, text boxes 1-3 are the input boxes and the code above shows how if the answer in the textbox equals the labels added together, you win. This code works -
I have created labels 7-12 now, and textboxes 4-6. How can I extend this program so it has subtraction as well?
If this problem definition isn't detailed enough, let me know and I'll add more detail to this description.
is there any way to extend upon a procedure itself?like i want to be able to do the following
Code: public sub test() msgbox(special())
end sub and it should popup a string, let's say "cool", plus i shld be able to use special() in every single sub but if we call special() from a function it should be rejected. how can that be done?
also, we should also be able to do the following
Code: public sub test() msgbox(specialvariable)
end sub whereby specialvariable is accessible by every sub.
How to extend existing components in Visual Studio 2005 to add my own features and functionality. For example, I want to extend datagridview control to include my own extra features.
I reference several 3rd party libraries in my application. I want to put all of these libraries in a folder that is different than where the executable file for my application is located. I would also like to put all of the libraries that are required by the 3rd party libraries (but not referenced by my application) in this same folder.
I need to be able to put the application (and the referenced libraries) on a thumb drive and run the application from any computer without any installation or registering of components. This condition is satisfied if I put all of the required libraries in the same folder as the executable.
For example, if my application is located at E:MyApp then I would like to store all of the 3rd party libraries in the folder E:MyAppDlls. Any way to store all (or at least some) of the libraries in a separate folder?
As topic says, I need to extend the features of a standard Silverlight ComboBox to also support Commanding. Since I follow MVVM I need my ComboBox to communicate the SelectionChanged event to my ViewModel.What would the code look like for doing this? I want to be able to put the Command attribute on my ComboBox XAML control.
In order to organize various methods of my MainForm class, I would like to categorize them into several files. Of course, the methods would still need to access form elements and additional variables I added in the MainForm class.
How to extend the session time. There are many form in my application like parent and child forms. So how can I make pop up to appear when session times out and the pop up should appear on the form where the user is currently in, when popup comes I have to disable all forms like(they should be transparent (i.e) user should NOT be able to edit them).
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If My.Settings.registered = True Then Form3.Show()
[code]....
This is my code for a trial application. The code is pretty basic but what i couldn't figure out was how i would be able to prevent users from changing the date to extend the trial ("error" i would be getting).
This has got to be one of the most frustrating issues with asp.net. I first got the error parser error cannot load default and as I have done before checked if the naming was correct in th bin folder and made the changes accordingly. Now I get the following error:
somethiing._DEfault is not allowed here because it does not extend class 'System.Web.UI.Page'
where something is the name of the project in the properties. I have the following code in Default:
Namespace FormDiscovery Partial Class _Default Inherits System.Web.UI.Page Shared settings As New System.Configuration.AppSettingsReader
[Code].....
Now I have deleted the project and other in the solution and created a new one and still this error and if I take the 'something' name away I get the cannot load default error.
