How can I block a column from a datagridview to accept only values like hh:mm style and nothing else. And how to handle errors when user is inserting something else than time format?
View 2 RepliesI have a script file which uses code similar to the C# language, using { and } braces to start and close 'blocks' of code. Note that blocks can be nested.[code]...
Is it possible to use regular expressions to parse the code and return the name of each block separately? So in the above example, it should return block1, block2 and block3 but NOT "block 2 contains" or "and another" (no nested blocks).

I am developing a project using VB2010. In the attached example I created a Form.
On tha form I put a GroupBox Containing a DataGridView.
I am trying to set, at Design time, the ColumnHeadersDefaultCellstyle Font of the grid, defining the Font, the size and the style (Bold). After saving the project or running it, The Font properties of the grid headers are changed to the Font properties of the containing
GroupBox.
Why is that so? How can I set, at Design Time, a different font for the Grid Column headers and the GroupBox?
To demostrate the problm - Try to modify the Font of the grid headers, in the attached example,
to "Bold" "Size 12", Run the application and see the result.
Some codes here on how could I validate my datagridview? I mean, a certain column on my datagridview should accept integers only, otherwise, it will return a messagebox. Kindly include on which event it should be posted.

I am trying to make a style that only gets applied if the parent element of the element that the style refers to, has another specific style. Kind of like in CSS where you can do ".class1 .class2" to specify that the "class2" theme only applies if it is within an element with the class "class1". I do not wish to use any form of external DLLs or libraries for this task. I want to know if it's possible to implement on my own.
I've tried using MultiTriggers with no luck. I have a style that applies to all TextBlocks. I want the textblock to do the following: If the font-size of the textblock is 11 and the parent element's style is "PinnedSuggestion", set the foreground color to "#FF505050". If the font-size of the textblock is 11 and the parent element's style is "Suggestion", set the foreground color to "#FFCCCCCC". The conditions that I have tried to write to make this work, are as follows (the font-size condition is true, but the other one is not). The conditions are inside a style that applies to all textblocks in general.

View 1 RepliesI am creating an application and am very new to VB. I have 4 buttons on my form which is like my applications main menu. I would like that each of the buttons behaves in the following way when there is a mouse rollover: The Button back color is changed from the default to Red The Button text is changed to Blue, Bold, and increases in font size I would also like all the buttons to go back to their initial state when the mouse leaves.
Another thing, instead of me writing code for each of the buttons event handlers (Mouse Hovers, and Mouse Leaves) is there a way I can write this code once, maybe as a function and then always call it for any button that I create from here on so that any new buttons take on this behaviour.

I have a VBA script that connects to a site.On that site, it puts in criteria to filter on a database. It then submits it.A pop up window appears asking to Open / Save / Cancel. I don't know how to interact with that window.It is possible to Save, and specify the download location without having to use Sendkeys?Note: There is no file to directly download. You have to run the report and it kicks back the file.I know this is VBA, but I think VB.NET has probably has the same result.
