Get The Printer State Correctly?
Aug 20, 2011
I'm developing a program (VB.NET Form) that has printing function, then i have to alert user when an error occurred such as paper out, paper jam or etc. I found that .NET has WIN32_Printer class use for retrieve printer information and status. I can get printer status (Idle, Printing) correctly except offline, but for DetectedErrorState... always get 0 if printer has no problem and 2 if any problem found. (from reference 0 means Unknown and 2 means No Error) How can i get printer state correctly? Is this related to printer manufacturer or their driver? Because their application can alert correctly, i guess that driver never return value to WIN32 Class.

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'd like to be able to specify two different printers for two different jobs. I'm using the following class to handle printing these, but regardless of what I do, the default printer is always the one that's printed to.[code]If I inspect my PrinterSettings attribute immediately before the call to DrawString, the PrinterName attribute is still correctly set to the printer I specify, but it's still the default printer that kicks out the job.

I'm having a problem over here; I'm developing a DirectX 9 application, and for some reason, I can't figure the way to close the application completely. This has never happened to me, to be honest. I am using Application.Exit(), which doesn't seem to do anything - it just closes the form, but the program is still running. I have also tried End, but it throws a run-time error I can't seem to figure out.

I have been making a text based noughts and crosses game and trying to convert an alpha grid reference into a number to run the logic sequence that decides whether the an input is valid. I am using the asc command to convert but it just keeps putting up the error: Conversion from string "a" to type 'Double' is not valid, when it reaches the line If (Asc(Left(choice, 1)) >= 65 And Asc(Left(choice, 1)) <= 67) Or (Asc(Left(choice, 1)) >= 97 And Asc(Left(choice, 1) <= 97))Choice is the input and has already been checked for length, whether it contains an alpha and numeric input (and where they are) and whether the numeric value is valid.

This form works in VB .NET
sendMsg = "<CStatus timestamp=""0"" " & _
"type=""login"" " & _
"cid = """ & cID & """ " & _
"key=""" & loginKey & """ />"
But I can't get it work in C#
sendMsg = "<CStatus timestamp="0"
type="login"
cid="" + cID + ""
key="" + loginKey + "" />";
It does not give the same effect. I want this as an output:
<CStatus timestamp="0" type="login" cid="var_cid" key="var_key"/>;
Is there any stringXml command in C# or another way to use double quotes in string?
Solved it with XmlTextWriter

I 'm having no trouble coding, I'm back to my initial printing problems. The program printed Avery labels in a variety of sizes. I created the label templates on 8.5 x 11 forms and then printed the forms. This cannot be done in VB 2008 for a variety of reasons:
1) The form size cannot be larger than the screen size I got around this by creating a new form class that matched my dimensions.
2) printform only does screen shots. This was a major barrier. First of all I can't get printform to print my custom form because it's not a member of system.window.forms.form, it's a class in system.window.forms.usercontrol. However, even if it was in the correct class, it wouldn't work correctly because printform in VB.net, does a screen capture of the form and then reduces the image on the printout.
So that is my dilema. I do not know how to use the reporting tool, but I can see that it must be binded to a database. Although my application does use a database, I want to be able to massage the data before printing it. And the application does more than just print labels. There are also custom reports that need to be printed.

Ive seen that people use Form.Close() and Application.Close(), but what if I have many forms, and I may have forgot to close one of the forms correctly, is there a way to exit the application that actually checks to make sure that all the processes related to the program are closed first? I read on another forum that Application.Exit() is a bad way to close the program, and I found an example code of how to do it the right way, but Ive never found this anywhere else before.

I have a issue with loading a collection. The issue is that when I load a collection up with multiple objects that the only items that are in the collection is duplicates of the last object that was added in. I was through the process of creating the new object and it is loading correctly but when it adds it to the collection, it changes all the prevoius objects with the current object. Here is the code that I am using. I have been messing around with this code for a day now and can't figure it out.

I have a single form called 'FolderSelector' with a label, textbox and a button.The problem I'm having is that everytime I run the application, the only thing that shows up is a blank form called 'Form1', the program runs everything it should do except to show the actual form which is really weird.Here's the code in case there's something in there that's causing it that I haven't spotted.
Imports System.IO.Directory
Public Class FolderSelector
Public Const SPI_SETDESKWALLPAPER As Integer = &H14
Public Const SPIF_UPDATEINIFILE As Integer = &H1
