View 2 RepliesI have a macro run program I have created using excel 2007.The excel version makes use of VBA designed userforms and macro code to run and it stores data within a worksheet.It populates some of the fields in the userforms from drop down boxes whose pre-populated values are stored within another worksheet in the workbook.If I was to create this within vb.net how would the drop down box values be stored? and also: would it be easy to have the userform on-close click event send the data to be stored in an excel workbook ?
View 3 RepliesNeed to design a program that can encrypt and decrypt messages stored in simple text files using a private key stored in a separate file. Software should also be able to allow the users to enter simple messages that either displays the encrypted or decrypted message. The encryption method should use a simple substitution method. It should be set out in the following format:
Example (the "@" is the separator):
@
The character The Code End of line
A @ 4gh EOL
B @ 84!9 EOL
Has to use the 256 ASCII character codes. The separator will be used to separate the character and its corresponding code.Here are the pseudocodes I have come up with:
� Read any private key file
separator = readline(file);
while not EOF(file) do
tempStr = readline(file);

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 5 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. I know I could just save all the data each time the program ends into an XML file, and load it each time the program opens.... but is that the best way? Can it be done with a database without having to constantly save or load a file?

View 1 RepliesI'm developing a project for gathering customer feedback using a Samsung Q1 Ultra, a cheap touchscreen PC. The project consists of two parts: a PC based application that builds the survey and stores the info on an SQL Server, and a survey viewer on the Samsung device which downloads survey data from the SQL Server and stores it on a SQL Server Compact 3.5 database.
My question is, how best can I transfer survey data from the SQL Server to the handheld device's database? Writing a tonne of code to copy data from one database to another seems overcomplicated - is there a handy function or somesuch that I can use to copy data from identical tables on these two separate databases?
I collect two sets of data from two different databases, This data is now in two collections. I then join/append the one collection to the other and then put it in to a list view.I really would like to order this list view by the first column without the click event.To make this even harder the First column contains Data that is DateTime and i have found that it orders the items by the day number and not the months or years or time.I have found one way but it then cause's me further agony when doing some checks upon the data within the listview later in my code. This answer is to rearrange the format to "yyyy-MM-dd HH:mm:SS" then using the listview.sorting = sortorder.

I am in the process in developing a new version of my software. I have changed my design of my database slightly (added a few new tables and new fields to existing tables). The issue is that my users have user data in the old Db that I would like to transfer to the new Db. Both Db's are access 2003. Because my software is distributed over a wide geographical are it would not be possible to do this manually
I have appended data between two different tables in a single Db, but not between two separate Db's.
I have an interesting project.I've been tasked to create utility in VB.Net. So far from what I can see, I will need two tables produced from data in other databases. The mockup was done in Access which has a unique way of treating all tables as local tables that can interact with one another without any serious side effects. Simply put, I can add three tables from three databases and create a relationship and query against them without any problems.I'm not allowed to write or create items on the Server, so I need to do everything within VB.NET. I've created a local MDF file that will be included in the project installation, but as I'm new to .Net. I'm not sure if this is the best practice.I was excited at the prospect that I might be able to avoid having an attached data source when I realized I could create a DataTable and call data from it. When the application shuts down, the table would disappear and the footprint would be virtually 0. But now rather than just selecting data from that table I need to now delete and insert data to the Datatable object based on AdHoc selections on the form.
