I have a form that uses the printer object and the print preview. A user clicks on a Print button, the preview comes up. This works fine the first time they do so, but if they click on this button more times, the output is overlaid ontop of the first report. The printer object is destroyed at the end of the print creation, and I have tried various other means to make sure that the page gets cleared without success.[code]
View 20 RepliesI have the following page and what I'd like to be able to do is that when the user clicks on the clear button that it disposes of the results of the datagridview and reloads the page.

i am new at everything VB.net/ASP.net. I have an ASCX.vb page that lets the user choose someone from a table. Once they do select someone, the page reloads with that persons information into another table below that one where they can submit an order for that person or remove that person. Problem being is that i wanted to store the users ID that are selected but it seems that everytime the page reloads to show an update, it dim's my array again back to default. This is my code once they choose a user:

I have a webapp in ASP.Net with a VB codebehind. I need a List variable I have declared to persist as long as the person is on the page, but currently any time a control posts back to the code, everything is cleared out. Can it be done with a Session variable? Those seem to me to be limited to base types, but I could be wrong.

I am continuing a previous thread to keep it from becoming tooooooo long. I tried most of the helpful suggestions offered by kind forum contributors but can't seem to make them work. I tried to analyze somewhat but it's beyond my skill level. So a different approach was to try to incorporate the code in the PrintDocument1_PrintPage event of my application that prints acceptably, but only prints first page of multi page document. I had three somewhat different approaches offered by John Anthony Oliver, ACAMAR, and Crazy Pennie. I cut the code and placed in the PrintDocument1_PrintPage event code. All three approaches made the "Printing"message box page counter go wild without outputing to my printer. Family Man Mike suggested resetting the variables after the e.HasMorePages=false line. I tried that approach but couldn't make that work for me, I really don't comprehend but made an attempt such as num_of_pages = 0, startVal = 0, endVal = 0. That had no affect on the functionality.

I've checked through most of the nfo I can find in forums about scaling a picture, but still haven't stumbled over the answer. ALl I want to do is print my form on the printer. The problem is I don't know what monitor the form is being dispayed on and how big or small the user has madt it. I just want it to fit on the printer when it is printed. Basically I want it to, "Fit the Page".
I thought I could do it by using a rectangle and adjusting the size of the rectangle to fit the 8.5 x 11 paper, All this seems to do is magnify my form on the printed page and clips the sides and bottom of the form instead of making it "fit" on the page. What am I doing wrong?

I'm helping the IT department at my school do an audit of all our printers (there are hundreds). They are all networked, so I wrote a vb.net program that sends PJL (printer job language) commands over port 9100 to all the printers to retrieve the page count. @PJL INFO PAGECOUNT actually gets the page count for all the printers, but for color printers we also need to know the color / mono page counts (number of color pages printed, number of black and white pages printed).... the number being returned by the PAGECOUNT command right now seems to be the total pagecount on color printers, so if I can find a command that will give me either the mono or color page count, I'll have the other number. I also need the serial number of every machine (the spreadsheet I'm working off of is unreliable). @PJL INQUIRE SERIALNUMBER actually returns the serial number for about half of the HP printers, and some random non-HP ones, but I can't figure out a way to get the serial number for the other 50%. I sent emails to some of the people who wrote the articles about PJL I was following, and they advised I try using printer spooler functions (from my brief google search it would appear these are windows API's that facilitate communication with a printer).
Does anyone have any experience with working with the Printer Spooler functions or know a PJL command I might have overlooked that will help me get any of the info I'm looking for?here is my program right now. Ignore GetSerialNumber2 and GetSerialNumber3... they don't work (well actually GetSerialNumber2 works on 5 printers... but yea). GetSerialNumber() is the one that gets the serial number successfully for about half of the printers. (edit: I took out those functions in the version I posted, along with some other stuff that wasn't needed for this, to fit the post size limit)
We would like to know whether there is any way to interrogate a Graphics object and determine whether it is to be used to print or to render to some other canvas. We're aware of an API call that can be used but would prefer to avoid that route if possible. There's also the possibility of simply passing a flag in with the Graphics object that is True from a PrintPage event handler and False from elsewhere, but that's not ideal either. We're looking for a managed property or method accessible via the Graphics class itself, but nothing's jumping out.

I am already using printDocument to print the image (System.Drawing.Bitmap). How can send use this HDC or DEVMOD with printDocument.
I already tried using the "PrintDocument.SetDevMode". it seems not be working.
1. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
I've hunted through this forum, MSDN, 'Help' (a misnomer if ever there was one) the VB Library and one or two other forums, which either baffle me with reams of code or suggest code to try which either just don't work or which doesn't declare all the variables and usually don't suggest what type of variable I need, it's all very frustrating
I have a program which opens up a webpage through a WebBrowser object in c#, and does a bunch of operations with it. Now I need to integrate this functionality into my own webpage.
That means that either I need to take the c# code, and somehow make it work in my webpage itself (put in a WebBrowser object, set up event handlers, etc), or I need to somehow have my webpage open this program on my server, fire an event to start, and receive input from it. It is very important for me to use a WebBrowser object (or even WebKit.Net) because there is a lot of javascript, etc on the page that needs to be processed.
What we want to do is save an entire control into Cache and recommit the properties on page load, including data items. But we'd like the controls to exist already in the page.
