I been playing around with some code I found on internet and I am probably almost where I need to be. Using the printdocument I am able to get the active form in my project to print. That works fine. MY nextr issue was to get the form to print so that it is Black & white. No shading etc.. So I found a routine on internet that will take image and turn to B&W. Problem: IF a text box fields background color is too dark then the entire box shows up in black. If a text box field data is Selected it also is too dark and comes out white.her is code I found for turnign to B&W

View 1 RepliesI am using the cursor converter to set both
dim cCon as cursorconverter = new cursorconverter
me.cursor = cursorconverter.ConvertFrom(myCursor.cur)
and
windows.forms.cursor.current = cursorconverter.ConvertFrom(myCursor.cur)
the reason for setting both is that otherwise the cursor will not always have the desired appearance. I know that cursors can be rendered in color, like 3D-Bronze, windows animated, hands and variations.

View 2 RepliesI have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?

I have a requirement to print a number of records from a database. Each record refers to a second database that holds x number of related records. Just like and invoice header and line items.
I first print the report heading on the first page Something like "Invoice list for May 2012"
I then print the Invoice record headings under the the report heading Something like "Inv# Cust # Cust Phone Address 1 Address2 etc"
I then print that data from the original recordset Something like 1234 DR127 555 555-1212 Somewhereville 245th street
I then print the Line item headings Something like "Ln# Item# Description Qty Cost Selling Extn"
NOW Here is my problem: I never know how many line items there will be so can not predetermine when I will need a new page. I do have a way of telling when I am at the bottom of a page by using the text height and incrementing a value for each line
BUT I cannot figure out how to break out of the line item loop, start a bew page then carry on where I left off.
Once all the line items have been printed I need to start the next invoice by printing the Invoice record headings again followed by the header data followed by the line item headers followed by the line items for that invoice.
I have said that the page break may come while in the line item loop but it actually cold come anywhere in the overall loop.
must stop the user from proceeding if the textbox is null,if the textbox has only spaces in it.i tried . trim but that doesnot work, still spaces are excapted as valid characters.

I basically have an application that generates reports in a .html file, I use a .html file for the ease of making tables and formatting text.Now I would like to introduce a way of printing the reports from my program. Because I use a .html file, the formatting would not the correct if I was to print it directly from my application (as far as I know). For this reason, I would like to print it just like my web browser would have in order to keep the tabular data intact and the text formatting.
View 1 RepliesI'm creating an application which has an scheduler to print and it checks if there is a pending job on the print queue before it prints the next file. I use a timer which checks if there is any file to be printed on my database. Example, the timer ticks and selected 10 files to be printed, it should print the 10 files 1 at a time, if there's no print queue, that's the only time the next file should print. I think another timer is required which will keeps on checking if print queue is done. How will i do this?

That mostly says it, I don't know much more to add. (-: The background is some random red after the execution of a sub routine. I then would like to have the backcolor dissolve from what ever value of red is present to a full white in about 1 second without showing other colors.(Unless it looks really neat...) Red could be anywhere from RGB(0,?,?) to RGB(255,?,?) when it starts to dissolve. Obviously the closer to 255 would make a smaller amount to change. However, I could be just as happy to see it go from RGB(150, to RGB(255, ?, ?) to get it started. The foreground is black numbers.
