View 4 RepliesI 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 --

I 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 RepliesI 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.
I was thinking about using an access database to store the data but I would like to know if there is a better way of storing data?

View 5 RepliesI've just finished an application which does everything I want within the Visual Studio environment now I need a way to store the data the user creates but I've never had to do it before and am a bit lost. I've spent days trying to use XML to do this but to no avail mainly cos my classes use ArrayLists as properties and it gets a bit beyond me. I've been told that ArrayLists were not the best choice for this and would be prepared to change my design if need be if I thought the end to this problem was in sight.

I'm creating a program that outputs Quotations (and other information relating to these 1. 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]...

x = len(this_is_a_list)
this_is_a_list.insert(10, x)
len is a function who count how long a list is. This list is 11 numbers long. I will now insert/add number 10 after the last number. The first number has the place 0. The second number has the place 1.Can VB.net do that? Check how long a list is?Delete a list?

View 13 RepliesCurrently I have a list of items that are based off of a structure of information. I have been putting off the saving function of my program until near the end to make sure that I have all the elements before I start worry about what needed to be saved. I am not asking for code, more for direction. Is it possible that I can load and save data directly to a database rather than have to hold it all in memory as a list? I have never worked with databases in vb.net, and wonder if there are places that would help with this under the requirements I need.
My program saves recipes into a structured list. All the listboxes and forms use the list to populate the correct data on them.

Can it be done with a database without having to constantly save or load a file?

View 2 RepliesI have a file which is opened and the bytes are loaded into a class.The file needs to be split into chunks, and there is a header which gives the locations and sizes of the chunks.Should I (upon opening the file) split the file into chunk sand store each chunk in an array of variables And then when I want to access the data in the chunks I just use the array.
or store all the chunks in one variable together and then when I need access to the chunks get the location and size of them and use that to find chunks each time I need to modify them.
I don't know if I can have several same forms to do the manager jobs, ACTUALLY THE STORE VALUES ARE DIFFERENT(those forms can have the independant data values to store into the forms), like if I can have the datagridviews to store the different values?
