Do All Programming Languages Use Static / HEAP & Stack Areas To Store Memory
Apr 9, 2012Do all programming languages use the Static, HEAP, & Stack areas to store memory? Does understanding this help me with debugging in any way? How do I query or access the memory in .NET would I ever need to do that? Or the memory addresses?What keywords would I type into Google to get more on how the .NET CLR uses memory?I'm learning Java and am trying to compare .NET and Java and how memory management differs and is similiar.
View 2 RepliesInputBox Function - Program - Allow User To Input 5 Payrolls For Store 1, Store 2, And Store 3
Mar 22, 2012I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

XML 6.0 SP2 - Create A Small Backup Before Data Is Syncronized To A Data Store?
Feb 14, 2011I have an application that uses Dataset.WriteXML to create a small backup before data is syncronized to a data store (less than a meg).This application has worked well for 5 years now, and all of a sudden with the installation of XML 6.0 SP2 the XML document is not working correctly.I have multiple tables within a Dataset (Company, Contact, Notes, etc...)When WriteXML is called, the first table should be Company, however, the first table is being named Contact with the Company Data in it. The Notes table is being called Contact and so forth. In other words it's not giving the correct names to the tables in the XML File.This appears to be a bug, which is causing great distress on all the companies who have been using this program.

View 1 RepliesBest Way To Store Data
Jul 31, 2011I hope this is the correct place to obtain a little bit of advice for a program I am looking to produce in visual basic 2010.
I currently work as a design engineer designing press tools and a lot of our designs are similer just maybe a feature, length, diameter change etc. So the design principles are the same for each product.
What I am aiming to do is program the 3D design package so that 80% of the tool design can be done using the program etc.
Now the enquiry I have is where would the best place to hold the standard data be?
For instance each press has a maximum blank diameter, shutt height, bores diameters in the bed and likewise each product type has design features with the same calculations such as length, pierce etc.
I have done a bit of reading and I have found that data can be stored into text files, xml files and databases etc or hard coded into the program.
I am looking to allow new presses to be added so the user would need to add new shutt heuights, blank size etc but the tooling would have to be unqiue dependent on the typs of stage. So I am wondering to store this information would a database be the best option even though the data will not be continually updated more a place for it to be retrived from excpet under failry rare circumstances.

View 9 RepliesWhy Is The MemoryStream Data Not Released From Memory
May 19, 2009Is 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.

Run Query On In - Memory DataTable & Server Data
Jun 14, 2009I wrote a procedure that builds a DataTable in memory using data stored on our DB2 database. The function builds a Multi-Level Bill of Materials (BoM), meaning that the data cannot simply be queried. The function works great and returns a nicely arranged DataTable object. However, I then need to query the in-memory DataTable against other tables on our server. What would be the best way to approach this problem? Should I make a DataTableAdapter for the Server tables and then build a DataView? I don't have too much experience yet with Data objects. (By the way, I looked into LINQ to DB2 and even installed IBM's addin's, but our server doesn't seem to support it at this time.)

What is the BEST way to read/write from a database (I only really know how to use Access but if XML or SQL would be better, I'm willing to learn). The database needs to be stored and accessed from the same state every time that the program opens. I've tried multiple different ways, both through DataAdapters (in code) to doing it through connecting the database through the Visual Studio GUI. Neither have seemed to work. Other people have told me that using DataAdapters and such aren't the best way, but no one has been able to tell me what this 'best way' is. Also, I need to somehow be able to link pictures in the database - apparently it's not easy to do in SQL?[code]...
