The problem I'm facing is that PrintForm has a shoddy quality while getting the printouts and PrintDocument takes way too long to get on receipt printed (Almost 5-10 Seconds!)I'm either looking for an alternative for PrintDocument or somehow make the PrintDocument run faster

What tools can be suggested to identify how long a group of method's are taking to complete? I have a large math calculation engine that calls multiple classes. I need to track down which ones are the highest cost of time.

View 1 RepliesStarting a few weeks ago, compiling a project (VB.NET, .NET 2.0, VS 2010) has taken several times as long as before. In Task Manager, I noticed ResXtoResources.exe taking lots of CPU for a while. I've finally been able to get some data on this using MSBuild's 'Diagnostic' output setting, and comparing that output to what I see in a branch from a few months back. Most striking are the final lines, which give timings. Before:
Target Performance Summary:
[..]
1395 ms CoreResGen 1 calls
1930 ms CompileLicxFiles 1 calls
2135 ms GenerateApplicationManifest 1 calls
2844 ms CoreCompile 1 calls[code].....
Both projects were compiled on the same system with the same settings. We've made numerous changes, to be sure, but nothing to the order of magnitude that would justify such a change in timings (and only for this one task!). I assume resource generation is getting stuck on something — a circular reference, a missing one, etc. I have been unable, however, to find anything useful on how to trace such a problem down to what I assume is just a single resource file.Short of looking through thousands of checkins or temporarily removing some forms (and thus, their resource files) from the project, is there anything else I can do to figure out the issue? I can't seem to find individual per-resource file timings.
Findings so far:I've created a new, empty project with all the same .resx files in place.The issue is not reproducible in .NET 4.0: compiling the exact same test project takes less than a second.The issue is reproducible in .NET 2.0 as soon as I also add one of the forms from the original project; apparently, it will otherwise not compile the resources "properly".Removing individual .resx files will reduce the timings 'proportionally'; that is: I have unfortunately not found a single file that is the culprit.
I am on one asignment of convering C# to VB.net and stuck up with this problem.C# application has one class having inline two dimensional array initialized with size 168X168. I converted same class to Vb.net. Now whenever I create instance of my this VB.net class, It take almost 3 minute.
To figure out problem, I put break point on sub new() (first line of my constructor), and behaviour is realy strange because it takes 3 minutes to reach at first point of my constructor.Whenever I comment out my large size array initialization code, It works perfect. Now please note that same code is working fine in C#. It is not taking even few millisecond to initialize that class.
I have the following in my little program:A form containing a button and a combo box where each item is a "year" ex. 2009,2010,2011...
When the user selects an item from the combo box, and clicks a button, an excel spreadsheet is displayed in a datagrid.
- Depending on the item selected, a different file is opened.
Now, my problem is as follows. Every time the user press the button, it takes like 50 seconds to open the file and display it in the datagrid.
- The file range is from A1 to J393 (a lot of cells)
The procedure reads every cell from A1 to J393 and puts it in a multidimensional array. Therefore, I would like to know if there is a way to speed up this process.Another thing, lets say I selected year=2009 and press the button.I wait 50 seconds approx.Displays the spreadsheet (corresponding to the year 2009) on the datagrid.
Then
I select year=2010 and press the button.
Wait another 50 seconds approx.
Displays the spreadsheet (corresponding to the year 2010) on the datagrid.
I am writing an application for managing mp3 files. I use AXWindowsMediaPlayer1 for playing files and UltraID3 for reading and writing ID3 tags. Every time the user selects to switch to next song, the ID3 tags of the current file need to be updated. My problem is with Media Player taking a long time to release a file for access after doing a "close". Currently I need to add a 6 seconds delay between the "Close" method of the media player and the ID3 tag "Write", otherwise I get the error saying that the file is currently in use. Anything less than 6 seconds does not work...
I attached a short version of my application which focuses on the issue.
I'm writing a program to search files.The result is saved in a text file.Everything it's working fine, but when I say to look for files/folders in C:* the process takes long time and in task manager it's displayed as "Not Responding", this is not true because I see that CPU and RAM are working with this process.I've disabled in DEBUG OPTIONS the line "ContextSwitchDeadlock" just to prevent the error message "this operation require long time ... bla bla bla".Is there any way to display a progress bar or something like that that shows the program is running and it isn't "hang"?Here's my code (in red the line where the program hangs):

I have a program that prints using the printdocument control. How do I check for errors in the program. Sometimes the program prints ok, sometimes the print does not print at all or give any feedback about the status of the print.
Bireirectional printing is enabled on the printer.
The program prints barcoded orders to a barcode label printer. The supplier's only cue to supply is the printed barcode label. I can see in the program that the orders are getting queued, and at certain intervals a timer runs to update each available order's status to "printed".As far as I am aware, there is no "Error" event of the printdocument control, and the printing is an asynchronous operation. So how should I check?

I am having problems trying to center some text. I created a printdocument and it has a company name and title and then other information I have the information fine but I wanted to center the company name [code]I know I have to get the width of the page then divide it by two and after that find out how long my text is then subtract that so it still prints center screen. Pretty much right now it prints out and runs off the right side of the page.But what I would like it to do is print in the Center but have equal margins on the sides of the page still.Just like clicking Center allignment on a word doc.
View 1 RepliesI'm sending a rtl text "Arabic" to a receipt printer. My problem is in selecting left and top coordinates for each line. If the paper width changes the whole procedure needs to be written for that specific width, because I'm measuring form the left edge. Is there a way in the printDocument object that flips the starting point from left to right?
p.s. the format string in the args.Graphics.DrawString() only select the direction of the printed string in case it has some numbers and symbols but it doesn't start the string from the right edge of the page.

I'm using the PrintPreviewDialog and am wondering how I can change a boolean variable after the PrintDocument has been rendered in the dialog window. I found out that using the dialog's Shown event fires before the PrintDocument has been rendered so the boolean gets changed before the document's been rendered. I can't use any of the PrintDocument's events to change the boolean since the preview dialog is not always used unless there's a way I can use the EndPrint event to detect that the PrintDocument's owner is the PrintPreviewDialog or an actual printer or something.

The heart of the program is here. I don't have the code for the SplashScreen, AboutBox, and the InstructionsForm because that is unnecessary. The main issue that I have is with the large EndSalesButton_Click event. The big block there is driving my eyes and brain crazy while trying to test the logic.

Then of course the line psize.height = 200 always aborts because 'Kind is not set to custom'.
