I have a datagridview with 4 columns bound to a datasource. In the first column the user can only type numbers, in the 2nd, 3rd and 4th only letters (done with keypress and editingcontrolshowing).
Now I want that the user's input in the last two columns automatically gets converted to capital letters, regardless whether he is using Shift or has Caps Lock turned on.

ByVal e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing

My only problem is that when I double click a cell in the 3rd or 4th column (those where I want uppercase letters) and then one in the 2nd column, the text in the cell in the 2nd column is showed in uppercase letters too.
Note: It only shows the already present letters in uppercase. If I type extra letters they will get normal font (so lowercase if I don't use shift or caps lock, and uppercase if I do use shift or caps lock). If I don't type any letters and unselect the cell the text changes back to as it was before selecting.
If I double click another cell in the 2nd column (after i clicked one in the 3rd or 4th column and then one in the 2nd column), the present text stays the same, so it don't get showed in uppercase letters.
how it comes that only the first time that I double click a cell in the 2nd column after i clicked one in the 3rd or 4th column the present text gets converted to uppercase letters and, more important
I need that a particular column in a DGV necessarily be written in capital letters, without the user having to press "BloqMay"... for the rest of columns the user will write normal.
I want to know on how to convert small letter to capital letters. I want to convert every letter automatically once I press the keyboard. Im going to wait for your replies.
how do you search a string for capital letters, is there a function I can use to return to me how many capital letters are in a string? I have tried searching this but as yet not stumbled across a function. Most functions I found converted lower case to upper case Etc. I thought InStr might be the one but still looking for information on that one. I did find something along the lines of .char.isupper but the textbox is .text A password 'rating' tool of sorts of which I use a counter so if I enter "STRing" in the textbox for example it will return a 3 add it to the counter and continue with the little algorithm which my rater uses to add up things such as numbers or special characters to get a final score and that indicates to the user how strong the password is.
Quick question here about how to get it to accept capital and lowercase letters. I am running code that has certain Customer Types such as "T". It returns different information for that customer. There are only 3 types "T", "R", and "C". The rest return the default information. When I enter "t" into the textbox it returns the default information, not the information for "T". How do I go about getting it to accept "T" or "t"?
If I have a RichTextBox and want output like the first line is a font with capital letters and bold, while the next line on the contrary, what should I do?
I want to do is have textbox1.text show 10-20 characters that are random letters and numbers when i press button1. I have tried to do this but I am not so great with generating anything that is random. If possible have it be a mix of Capital and Lowercase letters.
I'm searching for specific string method that ignoring the word if it was written in capital or small letters when I want to type this word in a field for searching purposes or when a user wants to enter its usrename in capital or small letters.
what i want to is convert this string to something like this

both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
Question regarding fluent nHibernate table mappings:Apparently I was under the mistaken impression, that with an ORM tool, such as nHibernate, one could gain database independence - at least in table creation.Now, I have an automated toowhich creates fluent nHibernate mappings for me.It also works fine (though only if ALL tables have a primary key...)
Here a good representative example for such a mapping as it is created by the program public class ELMAH_ErrorMap : ClassMap<ELMAH_Error> {
Right now im using code to count the instances of certain letters in column named "status" the problem is i use a filter to filter them by the date they were entered, but the counter gets ALL the instances in the DB not just the ones displayed in the datagridview.[code]...
below is my code, i want to get a record base on a specif invoice number?

way to return letters like a,b,c,d,.......,x,y,z,aa,ab,ac,ad,.......az,ba,bb,bc,bd,.......bz, in visual basic. I am adding them to the headers of a datagridview. Sort of like excel numbers the headers on columns.
It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

i have a datagridview with three columns. i set the first column to visible=false, so the user can only see two columns.when the user presses the tab key in the first visible column -- column(1), i want to ignore column(2) so that the user only tabs through the rows in column(1)i can't get it to work. it will always tabs through the rows in column(2) even if i use the column name.
I'm keeping track of some things that are numbered and others that are lettered; while NumericUpDown is perfect for selecting numbered things, I need an analogue for selecting lettered things. The obvious choice would be a listbox that just contains all the letters of the alphabet. But I need to show only the appropriate range of letters, so if I want to use a listbox, I need to write a function that populates the listbox with the first n letters of the alphabet; if n > 26, it should continue with aa, ab, and so on. How do I do this?
In my window application i have taken one combobox field with its collection as "amc", "war" etc. Now in my datagridview this combobox column is display as Textbox column, i want to change it to combobox with the above collection "amc","war". I have retreiving the result in datagrid through sql query, hence in datagrid edit column section we doesnot have that part to change to Combobox column.

Dim Comp = From C In db.Table1 _ Select C.Completed, C.Taken, C.Namne Datagridview1.DataSource = Comp
Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.
I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.
