View 7 Replieswhat I want to do is cancel a MDI child form closing when the 'X' at the top right hand side of the form is clicked.So, I use e.Cancel = True in the MDIchild_FormClosing event.However, the parent will not close if the 'X' button is clicked, and I noticed that the FormClosing event of the child handles 'Me', which I assume is the parent.Changing the handles 'Me' to handles 'nameOfChildForm' only generates an error Error: Handles clause requires a WithEvents variable defined in the containing type or one of its base types

I am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

I have an aspxgridview which groups first by year and then by month. Basically my query returns Month and year as seperate columns. Now if I return month as "January or February" then ASPxGridview does not know how to sort this.
I heard of custom sorting, but even then if I return month column as a number and use dataitem template to convert it to a name...it works but then when exporting it only exports the number not the dataitemtemplate.
I am trying to display an error message in the edit section of a ASPxGridView when a user has tried to submit invalid data.I have been looking around and have found one blog that allows me to place an error message in red once it has filed validation by throwing a New InvalidOperationException.
I am using the rowUpdating method as described in the blog, but the exception forces my code to stop the code in visual studio (like you would at a break point) and displays the message. Once I click play again, the code carries on and the program continues. How do I stop the application from stopping once the exception has been called and carry on.

I am using VB 2008 and have a datetime picker. I wam trying to use this value in an INSERT command to load in to a table but I just can't get it to work. I debug it out which shows something along the lines of "24/03/2010" but it just won't accept it. However, if I create a string variable e.g. strDate = "24/03/2010". it works. I am obviously doing something wrong in the conversion.

Any resolution to make the cascading dropdowns work as expected when used inside edit mode of AspxGridview. I am using DevExpress Controls.
My requirement is as follow:
If I select country="United States" then populate the "State" combobox and on selection of "State" populate the "City" combobox.
If I select "country" other then "United States" then populate only "City" combobox with cities of selected "country" and no need to populate the "State" combobox. Also I need to hide the "State" combobox. i.e. like
Country State City
ROW1 united states Alaska Douglas
ROW2 Canada Toronto
ROW3 Australia Sydeny
ROW4 united states California Yuba City
Same is required in Editmode also.

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.
