Is there any way to turn the damned error provider off when i try to close the form using the windows close button(X). It fires the validation and the user has to fill all the fields before he can close the form..this will be a usability issue because many tend to close the form using the (X) button. i have placed a button for cancel with causes validation to false and it also fires a validation.

What is the difference between ErrorProvider.Clear() and ErrorProvider.SetError(tBox,vbNullString)
Is there a preference for one or the other?
I'm having troubles with my errorprovider and i already found out what the problem is - the textbox is bounded twice (Display Member and Value have different binding sources) and so the errorprovider is showing the same error twice. If i remove one binding source,everything is fine.Any suggestions?Oh - I'm validating the columns in my DataSet.vb with DataTable_ColumnChanged Sub with table.setColumnError().Another problem ->I have a field (decimal) in my dataset that is optional (can be null). But if the user writes something in and then deletes it so that the textbox is empty, the errorprovider is showing the error "Input string was not in a correct format."

Ive been searching around Google and while I have found some answers, Im not sure how to implant them correctly.
I wish to disable the Close (X) button on a Windows Form. I read about ControlBox (I think that the property) but I perfer to do it another way.
I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.
View 2 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 set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?

I got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown". I have noticed it that it doesnt show error message for those form which have few labels and text boxes. It shows error message for those forms which have 1 menu bar, 2 picture boxes(one is 1280,1024 & another is 250,456), 2 group boxes, 40 labels, 3 combo boxes, 38 text boxes & three buttons. Please help me I need to get rid of this problem. Does it mean that I cant use unlimited control there in my form?

View 1 RepliesI have a form containing a date textbox and a submit button and a close window button. The date textbox onblur calls a javascript function which checks for date validation and some other logic and displays some alert messages. The date on the textbox is always selected and onfocus. My problem is when I try to click the close window button with/without changing the date the alert messages from the onblur logic are displaying and I am unable to close the window. I tried using onchange instead of onblur but onchange too works when a control looses focus. it works fine when I donot change the date but when I change the date and hit the close window button it too displays the alert messages and the window does not close. Please suggest me what will be my best option.

View 8 RepliesI've written a small program that monitors the customer field in Quickbooks and query's a database to determine if there are any important notes for the selected customer. This works fine however, I either need the messagebox or a form to come to the front of all open windows on the system to inform the user that the selected customer needs to be reviewed.
How can I ensure that a form (or messages box) that opens in my program comes to the front of any and all application windows that are open?

View 1 RepliesI have created a com dll in Visual Studio 2010, vb.net. The dll is supposed to compile in the framework 3.5 for X86 processor. Should run anywhere right? I reference this from an Access application using vba. All works well on my development machine. I must also say that the project references an eBay sdk dll called ebay.service.dll. This file supports converting the .net commands into the appropriate soap commands to communicate with eBay.
All this works well on the development machine when compiled. The files in the bin/debug folder are eBayListing.dll, eBayListing.tlb, and eBay.Service.dll. I can reference eBayListing.dll from Access and everything works well on the development machine. On the laptop I registered the eBayListing.dll and eBayService.dll using the visual studio regasm at: C:WindowsMicrosoft.NETFrameworkv2.0.50727RegAsm.exe. Both files appear to register as I get the registered message from regasm. I run this as administrator.
When I try to set the reference from the Access application in the VBA references I can only see the reference to the file as it was on my development machine. I can tell because it has the path the the bindebug file. I don't see the version of the dll supposedly registered on the laptop. The file obviously isn't there so I browse to the file on the laptop that is theoretically registered, but get an error.

I'm doing a simple calculator program calculating Pennies, Nickels, Dimes and Quarters. I made a Try-Catch statement so that if the user enters letters into the text boxes, they get an error message. However, if the user leaves one field blank, the error message still pops up. What's the code so that I can get Visual Basic to recognize that an empty field is the same as 0 so that that message doesn't pop up? [Code]. What do I need to add to it to get that Error Message to stop showing when the user doesn't enter a value into one of the text boxes?
