Print Log In Released Runtime?
Jan 7, 2011
When running a program in VS debug mode, I use the Debug.Print and watch the Immidiate Window. I'm sure there are more advanced ways to debug, but I haven't learned so far.
But I would like to know how is the best way to track both log of exceptions as well as in-code specific method print-outs (like Debug.Print), during "released" runtime; outside VS.
I would like for two purpose:
Write to log text-file
Write to UI window, like a rich-textbox.
Is this a case I should use Console.Writline? I have never used that, so if you could briefly explain if this is the right tool for what I want to accomplish, or what other ways I should consider.

There isa xml file about 30 mb size. we are reading text of this file and assigning to a string variable.Then it occupy sapce in memory. But after comes out from method memory still not released. I also set variable to nothing.It still not released.[code]When i close the application.Then all the memory release. Or when i use the GC.GetTotalMemory(True) after st=nothing. Then most of the memory release not completely. I am checking the memory usage from Task manager and process explorer.

i've got a Set and a Get in a property. I want to allow multiple threads to do Get anytime they wish to, however if any thread tries to do Set, all threads must not be able to Get/Set until the Set is complete.[code]the problem is that this is pretty inefficient because each request to Get will steal the Mutex and prevent other Gets until the stolen Mutex is Released. Is there anyway to just check if a Mutex is released instead of using WaitOne because WaitOne checks and gains control of the Mutex which is not what i want

I can define a NEW sub that runs when an object is instantiated. What is the correct sub to call when it is disposed? I would think a method named dispose, but I seem to remember somewhere that there is a better choice than dispose.
Why do I care? I want to be able to track when a given object is released.
With a form, I can use formClosing, but what about a simple class definition?
how I would know what to search for to have found it without bugging any of you? everything I tried resulted in way too many hits that had nothing to do with VB or what I wanted to achieve.

I want to display photos of people when the mouse passes over their name. I wanted to be able to size the picture box to be proportional to the various photographs and let the Stretch property handle the rest.I used the code above offered by John Wein to a question from 2009 to read the dimension of the picture It worked fine until I pass over the same person twice. Then I get an error that the file is in use by another process.I tried adding:
"BR.Close"
With and without
"BR.Dispose"
But the file is still locked-out on the second pass. I tried setting "PictureBox.Image = Nothing" when the mouse leaves the square, still the file is seen as in use and locked.

Is there something that needs to be done with the following code to release the memory it uses?
Dim objImage As MemoryStream
Dim objwebClient As WebClient
Dim sURL As String = Trim(m_StationInterface.PicLocation)
[Code].....
The code is on a popup form that shouldn't ever get disposed. A new image is loaded onto the form every time it pops up. However, the process size for the application continues to grow each time it makes it through that code block.
I've tried objImage.Close() and .Flush(), objWebClient.Dispose(). The process size still grows by a good 4mb after every call. It's like the old image is kept in memory.

I have a VB program that displays a PDF file. When the program is closed it takes 30 seconds or so before AcroRd32 process releases the PDF file. In certain circumstances if the program is restarted with in this period, the PDF file does not display. The specific circumstances is that I have a second program (re)starting the program that displays the PDF file.
a) Make the PDF file be immediately released when my program closes
b) When the PDF file is loaded test that it properly loaded so that it can be reloaded if necessary.

I've created a simple Windows Forms Application and the idea is I want to identify all instances of Excel, save any open workbooks to my desktop and close all the Excel instances down.[code]I'm pretty new to this C# business so hints on the following two possible issues I've identified would be much appreciated:The ForEach loop doesn't seem to be successfully looping through the XlApp.Workbooks collection as I was hoping.
It seems that I can't quit each Excel application which, with my current code structure, is causing an infinite loop. My suspicion is that Marshal.GetActiveObject() is locking it up and preventing it from closing?If nothing obvious jumps out then I might try the alternative method by Andrew Whitechapel mentioned and linked to on this thread.

I have a program designed in VB.net for a wafer probing system. The software has 3 main components that come standard and three that are options. When a customer decides not to have the three options they are disabled but still in the program. If at some point they decide to buy the options, one of our technicians would have to go there and be able to access the program with an administrative account to enabled the components.
Does anyone have any suggestions on what the easiest way to accomplish this?

I have been able to do the exercise's in the first 2 chapters and half the exercise's in the third chapter of the text book (programming in visual basic 2008, Julia Case Bradley & Anita C. Millspaugh). but this one is making my head want to explode. please point me in the right direction with this.
Heres the problem. The company has instituted a bonus program to give its employees an incentive to sell more. For every dollar the store makes in a four-week period, the employees receive 2 percent of sales. The amount of bonus each employee receives is based upon the percentage of hours he or she worked during the bonus period (a total of 160 hours). The Calculate button will determine the bonus earned by this employee, and the Clear button will clear only the name, hours-worked, and bonus amount fields. A Print button allows the user to print the form. Do not allow missing or bad input data to cancel the program; instead display a message to the user.
Here's my code so far. its giving me the wrong results. i have tried many different ways,(hence the commented code) but I just dont know where im going wrong.
Public Class VB_Sales
Const BONUSHOURS As Decimal = 160

Anyway, I was just wondering if anyone knows how to do these from a simple text box. i.e. 'TextBox1'.
I'm just learning VB and it's only a simple text editor but I can't find any good sites or posts that help me in understanding how to do it. These are not really covered in any of the 'beginner' books I have acquired either.

My instructor told us how to print documents and how to use databases. What the instructor did not mention is how to print or print a preview of records within a DatabaseDataSet. The book "Programming in Visual Basic 2010" does not explain how to print or do a print preview of Database Source records from within a form. The only thing I was told was to test the print document first before you try to do a print preview. Within a form I used a DataGridView to add, delete, and update the database. So now all I need to do is figure out how to print the updated records from the DataGridView and how to print a preview of the records within the DataGridView. So I hope my question is clear enough to give me assistance on how I can perform these two actions. Thanks this would be a great help, and since the class is online we can get assistance from any sources that we have.

Basically on my form I have a listbox containing data. Under the listbox I want to place a button named "btn_PrintData" or something to that effect. The user will click this, the print dialog box would come up and bingo they could print the contents of the listbox.

How do I print the page title and the header of a GridView on each print page?
I want to add page title and GridView heading on each page.
I used page break to break the GridView into multiple pages, but only the first page comes with title and all other are without header and title page.
For a dynamic GridView, my code uses AutoGenerateColumns="true".

I am trying to make a notepad type thing that uses tabs. Each tab has a rich text box on (After being added via buttons) but am really unable to find a way to get the print preview to preview a certain, single text box on tabs. And obviously i can't add them manually (that i know) as loads of new tabs can be added at any time by the user.
