Datagridview Column Restrictions?
Apr 25, 2011I've got a datagridview of 4 columns (bounded to a datasource).I've restricted the first column to only numbers The 2nd column can have input all but numbers The last 2 columns can only have letters. Also for the last 2 columns I programmed that the input is converted to capital letters.
See the following
Private Sub validatekeypress0(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
If Asc(e.KeyChar) <> 13 AndAlso Asc(e.KeyChar) <> 8 AndAlso Not IsNumeric(e.KeyChar) Then
e.Handled = True
[code]....
For the first cell I double click on to edit, the restrictions are fine, but as soon as I click a cell in another column it looks like the restrictions from the previous column(s) are also taken with. At the end, if I double clicked a cell in each of the columns, every column blocks all input.

View 2 RepliesC# - Handle The Line Restrictions In Richtextbox?
Jun 1, 2012Under RichTextBox_TextChanged event, I have
if RichTextBox.Lines.Count() > 2
{
//Message Box to display the user that you are typing more than 2 lines
}
so what i happens is when i have these data in
[0] - "East coast road"
[1]- "New York"
rich text box, when i click Enter, seems it goes into this state
[0] - "East coast road"
[1]- "New York"
[2] -""
and I get the message pop up box saying can't have more than 2 lines, however the last line is just an empty line? How do i handle the line restrictions in rich text box or how do i ensure that when the user clicks enter I don't move to the next line and move to the next line only if there is 1 line in the rich text box?This returns count as 3 where in there should be only 2, how do i eliminate that white space next line?

View 1 RepliesVS 2010 Restrictions In A Query From Access To VB
Jun 8, 2011Is there a way to make specific queries from a specific table to another, and then export it to VB??. I have an access database, in which I have 4 tables and 1 query. There is one table called "Customers","Gears" and "Articles"; the last one is the relationships with the ID between the tables from Articles, Gears and Customers, becuase a customer may have more than two Gears, therefore the Articles as well.
So in VB I made an interface in which it conects to the database to show in a combobox all the customers, after that if I choose a customer, then it is supposed to show de gear in a listbox which the customer has, but the problem is that it shows all the gears from the query and not the specific one from that customer, also it repeats in the listbox the same gear twice or more. I think it is problem from my query, but I really don't know how to use very well Access, so I am depending on VB. This is the code that I got so far (Note in my

Asp.net - Restrictions By File Extension In Server 2008?
Sep 6, 2009I am having problems downloading files possibly due to the file extensions not matching the actual file. What is happening is the File.Exists check is returning false for these even though the named file does exist. Is anybody aware of anything in IIS or even IE which would cause this? I have seen this with .txt, .exe. and .avi files. The .avi works of as long as the file really is an avi and not renamed from something else.

The problem I have is that the user still has the possibility to place restricted characters in a column by pasting them in (with ctrl+v or right click-->paste), because the keypress doesn't notice the pasting.What should I do to make it impossible for the user to use restricted characters? In other words, how can i check the text the user wants to paste in a cell (cause that's the only other way to input data I can imagine)

View 2 Replies.net - ITextSharp Overlay Image?
Mar 15, 2011I have an instance where I have a logo image as part of some artwork..If a user uploads a new logo I have a form field which is larger than the default logo.I then use that form field to position the new image.
The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo..
what I have done is:foreach (var imageField in imageReplacements)
{
fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null);
fields.RegenerateField(imageField.Key);
PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber);
float[] logoArea = fields.GetFieldPositions(imageField.Key);

The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.is there a way to set a stacking order on layers?
