View 6 RepliesI have a button on my form where I'm showing a ContextMenu when the user left clicks on it, I'm actually using MouseUp right now to show it.What I would like to have happen is the user click on the button, the button stays pressed while the ContextMenu shows, it returns to normal when the ContextMenu closes (Either a menu item was selected, the user hits the escape key or they click/tab to somewhere else). Also I'd like to position the ContextMenu in the lower left corner if the menu opens down or the top left corner if it opens up. So the left edge of the ContextMenu is flush with the left edge of the button.Moreso the button staying pressed until the ContextMenu is closed.
Edit: I'm also ok with this being it's own control inheriting the FW's Button that used the assigned ContextMenu as well.
I have an global array of points that i want to plot in VB. say X and Y points, and typically they have values of +/-12000. Now I've not done graphics work for a long time and when I did, I used OpenGL with C. Now I need a GUI i'm using VB 2008. Firstly, what's the best method of rendering the array of points? should I use some port of OpenGL? GDI? or what?
Secondly, can I simply print to perhaps a Panel on hit of a button? Thirdly, do I have to place any line drwing code in an "OnPaint" event handler? Finally (for now) if my array represents points in a space much larger than the painting surface, how would I scale and scroll the final image within the the proposed Panel? I look forward to your advice.

View 2 RepliesThis my first time using a DatetimePicker so hopefully I'm missing something obvious.I have a bindingsource that has a datetime field that is set to use the short date format. The field is bound to a datetimepicker control.The problem is if I click the Add button on the navigator a new record is displayed and the dtp shows the current date. But if I then save the record the date is not saved to the database.If I go into the dtp control and select a date, it saves the date just fine.

When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

View 6 RepliesI want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.

1. Retrieving data from an .mdb
2. Displaying the table(s) in a datagridview
3. Populating an array of structures with the table data
4. Searching the array of structures for a member value equal to a string
5. Displaying the matching array elements in a listbox.

I have a basic window that has 20 buttons (One, Two,.....,Twenty).Currently if you click on a button its background color changes, and changes back on next click.I'm looking for a way to make it so when the mouse button is held down I can drag across the screen and it will change every button I hit.Disregard the "Shut Down", "Restart", "LogOff", "Clear", and "Invert" buttons. This idea doesn't apply to them.

View 1 RepliesI am using Visual Basic.Net 2003 with an Access 2000 database.
An integral part of the program that i'm working on is a DataGrid which I am filling from three different queries, based on the user's input. The Grid properties are coded with specific requirements for each of the queries. I have two simple (hopefully) problems.
1) There is no scroll bar on the grid and I can't find a property or event that will allow me to add the Vertical Scroll Bar. How do I do that.
2) The grids contain only four columns each. I want the user to be able to click on a cell and populate four string variables.
