XML 6.0 SP2 - Create A Small Backup Before Data Is Syncronized To A Data Store?
Feb 14, 2011
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.

I am a beginner on Visual Basic but was able to create the 'skeleton' of the application I need to build. Basically, it is an application dedicated to keeping a check on the vinyl I have. When I buy a new record, I want to effectively 'Add New Record' on Visual Basic and be greeted with a page consisting of various forms such as 'Artist' and Title'. Once these are filled in, I want to click 'Enter' and for all that information to be converted to one of the pages within my application.
Here's an easier look at it...
There are LPs that have 10" and 12" sections.
There are singles that have 7" and 12" sections.
In the 'Add New Record' page I want to also have a drop down list with the above elements in, once 12" LP is selected and all the other forms are filled in and I click 'Enter' - I want the application to send it to the 12" LP section of the application.

I want to create small database which handles Student Attendance Record it will store the roll calls of students on daily basis that teachers collect from the students in the class on paper and then later transfer it on computer .So my database Must contain Month, Year, Program (BCS, BIT, MS, MCS, MIT etc) Batch (1st, 2nd etc) and Subject (English, Math, Geography etc)
Suppose I want to Search for the Attendance Sheet of any month, year, Program, Batch or Subject, it returns me the required dataSo i come up with the Datadase which includes 5 dimension tables and one fact tableDimension Tables1. Student (StudentID, Name, other Attributes)2. Program (Program_Name, other Attributes)3. Date (Date, Week, Month, Year)4. Batch (Batch_Number, Description)5. Subject (Subject_Name, other Attributes)Fact TableAttendanceTable ( StudentID, Program, Date, Batch, Subject, Status)but the problem come when certain columns are repeating again and again which is time consuming for database operator and shows inconsistent behaviour of database.
Look at it: my Fact table would be like this [code]....
problems:1. The StudentId is repeating which shouldn't (Primary Key),2.It wastes a lot of time coz i'm repeating the data again and again Like Program, Date and Batch which shouldn't be in consistent Databases.

I have written a small project that saves data in a data set, this part works fine, but I have some errors with the code I have written for importing excel data to the datagridview and exporting data from the data grid view.
This is a test project for me to learn how to do this stuff, so I will post the code for the entire project so you can see what I have done from start to finish.

This error has me completely baffled. There is no indication (that I ca FinD as to what field won't handle the information. Heres the situation:I am using an Accees query to insert a new record in a table with 49 fields. Of these fields, 1 is an integer, 7 are booleans and the other 41 are text fields. The text fields represent either Time of Day or a Timespan.
My field sizes are:
For time of day 8 digits(example 08:00 AM)
For a time span 5 digits(example 03:30) I will never exceed 2 digits for
hours
I have checked every field in the dtatbase and they are all as noted. I am at a loss as to how to proceed.

Is it possible to use VB code to code an application that can merge Hex data from a small (50kb) .dat file with the hex data from another small (50kb) file? This would require designating specific offsets, which I can pre-program, but If I could have user input this would be preferred.
Example.
Hex_1.dat
00 00 00 00 00 11 11 11 11 11 (Offset = 5)
Hex_2.dat
22 22 22 22 22 33 33 33 33 33 (To offset = 5)
Result file
Result.dat
11 11 11 11 11 22 22 22 22 22

Is there another way to easily make a POST request in .NET other than the WebRequest class? I have a very, VERY small piece of data I need to post: password=theword but WebRequest randomly, and I mean randomly, drops the data when posting to my server. I've tested it by using a chunk of code from my server that dumps the request to a console, and I can that the client is sometimes sending and sometimes not sending the POST data.The code that I'm using that uses WebRequest works in another project, when talking to IIS. The server being talked to (a minimal web server in another system) responds properly every time I POST data to it through Firefox. I've got a function in the same project that fires off a GET request, and that works. It just seems like my POST function isn't completing the transaction...something I've noticed in the past when asking WebRequest to handle small strings.[code]

i am writing an application that will need to store less than about 1mb of data. this data will be read and edited by the user. this data will be very simple ascii data. the application is in vb.net on a windows-form. the data will be stored locally on the person's computer.i have several questions.what kind of encryption method should i use to store the data? the user wants something that is not too powerful, but not too simple either.how should i store the data? why not just write it to some file and encrypt it using some medium encryption method?is application settings data encrypted? perhaps i can store it that way? is it suitable to store about 1mb in application setting data? how would i do this? which variable would i use?

So, I have a little issue.. I can't currently explain it using the software I'm developing because it's "internal"... So I'm going to describe it as an email serverAnd the email server has a fair number of email accounts, and I want to save the accounts emailFor development, I've been saving it all in a list of a structure (this sounds worse than it is, the data actually is no more than 120 bytes per "email")

I will be using .Net to communicate with a small unit that outputs data via a serial port. I have used an application that monitors the data between an application and this little box. What I see is functions such as IRP_MJ_CREATE, IRP_MJ_READ, etc. At first I thought I needed to build functions and I would send these via the serial port (a novice thought) now I see that the above functions are part of the Windows Driver Kit. So is it true that I call these functions in my code and then the underlying drivers communicate to the serial port and the approppriate data is seen at the serial port. So for .Net (VB) I need to find and use the appropriate functions and communicate to the serial port.

I have a small database program that gets data from csv file, I created a function that formats the font color of textboxes based on dates and values.
CODE:
I place this in text changed event and I have a problem implementing it, because the date conversion will not take place until the data is loaded. The second part works but not the first(Date) part.
I can create a button and use its click event to format the text boxes just fine, however i wanted the text boxes to be formatted on the fly . The problem is no matter where i call the function the date conversion wont work.

Currently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.
