VB 2010 Express - Create A Simple Local Data File On PC Using Mysql
Jul 15, 2010
I have been reading about ADO, SQL, datasets, data adapters etc and have gone into information overload. My next step is to create a simple data file of my own that I can manipulate, update, sort etc in VB Express. Do I need another piece of software? I read about MySQL, which I understand is primarily used to access databases on the net, but can that be used to create a simple local data file on my PC? Can you simply hard code something in VB Express?

Im learning Visual Basic 2010 on my programming class and we reached the part of file handling. Here i tried to make a simple program that can create a text file with the content of what i type on the textbox, basically i create the file if it doesn't exist, and if it already exists i append the content to it. Once the file is saved i can read it using the "Open" button. Unfortunataly, whenever i try to create the file, the compiler gives me an error saying that it cannot modify a closed file, although i've followed up the execution instruction by instruction and i can't find the error.

I am trying to create a simple countdown timer using vb 2005 express edition. I think the code is fairly simple but I have fallen at the first hurdle. How do you display the result, i.e. which control do you use? Tried label and textbox but both return the error: "Value of type [integer or long] cannot be converted to [textbox or label].

I am able to copy the complete online mysql database to the local ms access database, but the problem is that the local database needs to be emptied before the new data is being copied. And a progressbar needs to display the entire progress. Here is the code what I have now:
Private Sub StartScreen1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I am trying to connect my application to my database that's hosted on my website through another host. I am using the System.Data.SqlClient Namespace, and I have tried about every connection string possible, and I either get a long delay (About 30 seconds) before the main form displays with a warning in the Console box or it just gives me the warning and loads fast. Either way, it's not connecting.
code:
The x's represent just a masking. The server value is the ip address of my website. Basically, I am wanting this app to connect to my database of my website and it will be used to compare login information as well as the status of the logged in account (blacklisted, active, or needs to be activated).

I am trying to follow this userguide url... to basically build an application that will allow users to connect to my database, from an exe file. I'll try to explain as best i can. The plan is, users will launch an exe file that i have built in Visual Basic(VB) 2010 Express. When they launch the application they will see a 'login screen'.I am following the example guide (see link above), and will customise it once i can connect to the database. For some reason whenever i connect to the database it gives me two errors, the first is if i use the 'debug' mode in VB to test the script (note it doesn't produce any build errors), the second is if i build the application and run it as my users would.
1)Error Connecting to Database:Access denied for user 'mike'@'92.**.**.***' (using password:YES)
2)Error Connecting to Database:Unable to access any of the specified MySQL hosts..The ip address starred out (*) is my local machine ip address.The server is the server in which my Database runs on. 'mike' is a listed user on my 'user' table, the password i use is the password assigned to this user on my table.
3)I've rebuilt the whole VB project, but still no joy, wern't expecting it to as there were no errors generated.
4) I've read, but don't really understand that it could be something to do with my database not being able to be controlled remotely, only locally. I started digging into 'Access Your MySQL Server Remotely Over SSH', didn't really know if i was going completely off the mark, it didn't mention needing to do any of this in the guide i've been following, but just a thought. It might be the case as i've tried to access my database through a programme called MySQL Administrator. I punch in the host,username etc and connect to my database, for some reason it won't allow me to add new users, could this be because i can't control my database remotely? Would this stop what i'm trying to do working?
5) When trying to install the MySQL.Data.dll file i had great difficulty in choosing one and finding it, adding it to my project using the 'Add reference' in VB. Finnally got it how it should be (i think), installed MySQL.Data.dll Ver 6.1.2.0 into my project.

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.

Each year I have to create 1099s from a legacy system. So in the past I had Foxpro code that ran out of a directory near where the Foxpro dataware house was. In 2009 we moved to SQL so I have to convert the code to VB and SQL
But I need to still store the text files and the report and I wanted to save settings in this "working directory"
[Code]....
Does this seem like the propery way to do this?
Finding documentation on XML is really difficult, because there is so much yet all of the examples seem to do it a different way.
