View 2 RepliesWithin our application, some of the object's text are effected by users with "Large font" turned on under Control Panel>>Graphic Properties. I can't determine what is the trigger to this behavior. I have many forms including TableLayoutPanels, ComponentOne Sizers, some objects with DOCK=Fill, and AUTOSIZE=TRUE. I wrote a simple Hello World form, and it is not impacted by the "large font" setting.

View 5 RepliesI am writing a program that will read and write to a file using the My.Computer.Filesystem namespace, and when I append my data file with the code shown below under SaveFile subroutine, it sometimes places extra ControlChars.Newline at the end of the appended text. Sometimes it places one extra newline, and sometimes it adds 3-6 newlines. I have tried everything I can think of to make it add just one newline at the end of each append, as I will be using the newline char to flag each entry on retrieval. I am working out some algorithms in this project to use in a project that will keep track of data in a file using csv format(just practicing saving/retrieving data from a file). The extra newline characters that are added will become a problem when I start to sort the data to display. my xSaveButton click event:

I have a label which appears full screen on a projector (VGA 2). In this label I will be sending strings. Some one liner's, some wrapped paragraphs. Some multi-line with carrage returns.

View 10 RepliesI am using a stored procedure to fill a dataset with a large amount of data (47k rows and 8 columns). I am needing to fill two tables with the results of this stored proc.One table will have data representing 47k reps that currently have credit for a transaction. The other table will be a mirror copy of the 1st table with 47k reps that were supposed to get credit for a transaction. This application is going to take credit from one rep. and give the credit to the other rep record in the 2 mirrored datasets. It's taking 30 seconds for the data adapter fill method to return records to my application. I would like to reduce the amount of time it takes for this request to process.

View 4 RepliesI am making an inventory program in which there's an ItemMaster and Sales Form. Currently there are 15000 records of items(increasing daily). I want to display all the items in the sales form so that the user can select an item from the list for billing, and also in the itemmaster so that if the user wants to edit any item then he can select it from the list.
I can make a common list form for both sales and master, but i have to load the data from the database into the list every time the list is displayed(which is taking lot of time), so is there an better way to do it.
Is there an easy way to insert a line into the very beginning of a large file?I want to insert an XML header line into XML files that my program processes (These files can be very large, so reading it via bitstream and writing it out is not a good option).
File.AppendText makes it very easy to append lines to the end of a file, but I don't see anything for inserting text.I wonder how does say Access work in processing say a 50 meg access database file? There must be a similar process where you can insert data anywhere inside a large file.
How would I use the BinaryWriter to append binary data to a file that is very large? Say a file that is 3GB in size. The BinaryWriter's write method will only accept an integer for the index value. I've attached a screen shot of what I'm talking about. If I were to enter a value that exceeds the size of an integer on my 32bit Windows XP system, which I believe is 2147483647 it will reject it right?

page 2 : page header+ table header + table detail(5 list data) + page footer
page 3 : page header + table footer + page footer ( this is the error)
I also try to print the report and its print 3 page.

View 8 RepliesA co-worker is having a problem trying to display the time in a label. He wants the AM/PM to display smaller than the time numerals. Neither of us knows of any way to change the font size within the same label, so we tried using two labels. That works for the different sizes, but we can't seem to get the appearance to 'flow' correctly without overlapping the labels, and then part of the text gets cut off.
We tried setting the padding to 0, but that still leaves a noticeable gap. We tried setting the background of the front label to transparent, but that didn't work for some reason. The left label (time) in right-aligned and the right label (AM/PM) is left-aligned, and that's as close as we can come.
Any way to either change the font size within one label or to overlap two labels without one obscuring part of the other? Or, maybe, a way to create a label so the text actually starts at the very edge of the label? (I'm doubting this last-I suspect the problem is that each character is defined, by the font, as occupying a 'block' of space.)
I have the following string which i want to convert to a Font
[Font: Name=Segoe UI, Size=14.25, Units=3, GdiCharSet=0, GdiVerticalFont=False]
I need to use a richtextbox, not a normal textbox because of the way it keeps the caret position, from line to line. But I need to keep the text at the same font all the time even if it is pasted. At the moment I have it selecting the entire text and changing the font to the original (Lucida Console) but it look horrible when you paste into it as it flashes blue.
View 2 RepliesHow do I make it so that each item in a listbox can have a different font color? This is the only basic code i know that can change the font color of the listbox items.

View 11 RepliesI have set my forms font as "Segoe UI, 14.25pt" and have just placed an single label on the form.
Upon placing the label by default it gets the forms font i.e Segoe UI, 14.25pt
i have placed the following code on the labels textchange event
Private Sub Label1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.TextChanged
Dim f As New Font(Me.Label1.Font, FontStyle.Italic)
Label1.Font = f
MessageBox.Show(Label1.Font.Name)
End Sub
Now when the form is loaded , i get a message box showing the labels font name as "Microsoft Sans Serif"
The labels font size also changes to 8 but it is italic.
Why is this happening? And why does the textchange event occur on the form load?
I would like to upload files using the ASP FileUpload control. However, if I try and increase the limit to about 10000 kB, it doesn't work and accepts files only upto 4 MB in size and I get an error saying that the connection to the server was reset. I referred: [URL]..but when I modified the web.config.comments file, nothing happened. Where am I going wrong?
Also, I wanted to know how this would work when I deploy it on the web server. I'm asking because in the code behind, I'm still giving a hard coded value for the path where the file is to be uploaded. How does this work?
I'm making a seat booking system in vb.net (WinForms) and I need the user to be able to select the seat they wish to use and for it to change colour (so they can tell that it selected).
I began to try using buttons, but 480 buttons seriously slowed down the load time for the form. I then tried a data grid view with buttons in the rows/columns, but couldnt make that work properly.
Would it be worth trying to use 480 picture boxes and change their background colour? Or would that just slow the form down the same way as 480 buttons?
