I want to place 24 check boxes on a form. I want to enable drag and drop for each and place the code to handle the drop on a customized check box, then create each check box from the custom check box. I understand how to create the custom check box, my dillemma is I would like to be able to drop the new control on the form using the form designer IDE.
View 2 RepliesI have created a customized control in which i have used some different property names. For eg. if the actual property name in the base class is "Text", i have used the name "CtlText" by internally implementing the "text" property with some additional checks. Now i want the user to use only "CtlText" property during coding. Currently the user is able to see 2 property with same functionalities.
Is there anyway i can surpress the using of a property during runtime?In design time we can hide it using the "Browsable" attribute, but i need to hide the same during runtime also.
I am creating a timesheet using a datagridview control, the user must enter the time in the cells for the code to process. The control however converts the data to a string even though the defaultcellstyle.format is "t" for shorttime. I need to get the control to accept time in various formats and covert it to a standard format. If the user enters 8.00 the cell should display 8:00 am, if the user enters 8p the cell should display 8:00 pm.
After entering the data the user clicks a button to process the data, the code checks each entry to ensure it is a date (using IsDate) and performs some calculations based on the times entered by the user. the information is then stored in a table. My problem is the datagridview control converts the cell entries to strings but I need it to retain the datetime format as I get a casting error when I try to use cdate to convert back to date.
I want to create a DataGridView control array on my form at runtime? I am fairly new to vb.net.
View 8 RepliesI have a DataGridView control (DataGridView6) that displays a list of managers. I want to generate a new DataGridView everytime I add a new manager to the list and put it in a specific place on my form.
EDIT: say if i have a main datagridview, and i want to add another datagridview of the same size directly below it, how would i achieve this using the event handler method described in your answer below? im not sure if this is the most efficient way of displaying new members in the program though...
I'm developing a program with a team in Visual Basic 2010.
What i wanna do is to create a textbox (inherits from textbox) with additional one property called MDIStatusInformation which is used to display a tooltip text in a status bar at main MDI form.
When i use this tag <Browsable(True)> _, the control property not list anything there.
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:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D
[CODE]...
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.

Suppose I have a Microsoft Expression Blend. Is it possible to create a custom control (such as a button) in MSE Blend and then import it to visual basic 2010?For example, I want to create a custom shape button (different from what is available in the toolbox in VB2010) (like for example a pen-shaped button) in MSE Blend. Can I import it to VB2010 to be used with Windows Forms Projects? If yes, how?
View 1 RepliesI'm attempting to create a customized dictionary object, because I want to add some code to the Add routine, and I can't just inherit because Add is not overridable.
So I'm creating a class that implements IDictionary. Already I am confused, because Dictionary implements a lot of interfaces, listed below:
Implements IDictionary(Of TKey, TValue), ICollection(Of KeyValuePair(Of TKey, TValue)), _
IEnumerable(Of KeyValuePair(Of TKey, TValue)), IDictionary, ICollection, _
IEnumerable, ISerializable, IDeserializationCallback
But IDictionary inherits ICollection and IEnumerable, so why implement all three (and don't they have overlapping methods)?
#2, when I implement IDictionary, the code fills in two Add methods (one for the ICollection add of a keyvaluepair, one for the Idictionary method). Apparently both these add methods are required for Idictionary, yet a regular dictionary (which implements IDictionary) only has one Add method that I can see. I actually would like to have only one Add method if possible. Why am I being asked to make two (and that's before all the other interfaces have been added)?

I need the output in desired format as shown in image2. Check the attachment. This should work for any number of records.
I've been working with System.Drawing for awhile and like to think I have a good handle on it; I've created classes that draw grids, write text in gridboxes and rectangles, convert rectangles to circles, fill areas with color, etc. What I don't have is any sense of artistry at all, and I don't have the slightest clue how one would use System.Drawing to draw a rectangle and then color/slope the edges so that it looks like a System.Windows.Forms.Button would, or how to make it look like it's inset deeper than the surrounding Form, like setting a Panel's BorderStyle to Fixed3D.

I have a dialog that gets called from time to time. It is only created once, and then shown or hidden. Depending on the current conditions, when I display it, I need to disable the controls on it so that the user does not make any changes.I have code that checks the condition and sets the enabled property to false for the controls. There is a DataGridView control on the dialog, and for some reason, it stays enabled and allows changes. Does anyone know why, or what I need to do to get it to not accept any input?

View 4 RepliesI have a datagridview control on my form which i have populated it with values from a dataset. Now i am using a button to delete these values from the database which is working perfectly for me but the problem now is anytime i delete the old value still shows in the datagrid which shouldn't be so so i wrote the code to refresh the grid after deleting but is still not working for me as i want.
I am using this code:
Me.UserAccountsDataGridView1.Refresh()
But onething is the value i deleted doesn't show when the form reloads again. but at run time it still has the old value in it again.
Is it possible to add Treeview Control in the DataGridView??
View 1 RepliesI've been working with this for a while now and have finally come to you for help. I have a custom control that inherits from a label and I'm trying to use it in a datagridview. I have followed this example and have tried to adapt it to my needs.
The custom control in this case is a label with a boolean type property named Value. When value is true, the label.text = "ON" and the color is red. When value is false, the label.text = "off" and the color is transparent. This is the effect I need to show in the dgv.
I have attached my developing project and would like you to take a look if you can. The project has a single form with the dgv, the custom control and a button on it. When the button is clicked the value of the custom control toggles. The control on the form changes color and text as it should, but the cell in the dvg simple changes text from FALSE to TRUE.

Working on getting a legacy app up and running again for work. I'm getting an error at run time that I can't create an activeX control. The suspect call is

I did a bit of googling and found that SQLDMO should be in a SQLDMO.dll. I've got that DLL referenced in my project but it is still failing.
