MySQL VSTA App To XP Application?
Feb 19, 2009
I have a application developed in VB.Net on Vista that is running on XP. While running the application on Vista the application works perfectly. While running on XP I get the Microsoft has encountered an error dialog box. Any ideas why I am getting this error.Both XP and Vista machines have .NET framework 2.0 installed. The application is also using calling MySQL. I have installed the MySQL connector 5.0.9. If I do not use MySQL everything seems to work on both XP and Vista machines.
I wish I could give you more information but I just don't know what else to post.

It's been a while since I have posted. Good to be back. I am doing some scripting work using Visual Studio 2005 Tools for application. I am having an issue outputting to the debug window. My line of System.Diagnostics.Debug.WriteLine("Test") I have the output window open when I start debugging and am using the debugger. What happens is the debug window seems to go away when I allow the line to execute. After the line executes if I go back to the output window nothing is there. The message does not go to the Immediate window either.

What i have going on, is i have a MySQL connector as a resource on my application, and im basically trying to connect to my MySQL server, to either a) register a new account, or b) check that the account exists and they are premium, and login, Now what i have run into problems with is: My MySQL Database Name has a _ in it which VB is not allowing for some strange reason.
The code i am using is below
Imports MySql.Data.MySqlClient
Public Class Form1
Function UpdateRecord(ByVal query As String) As Integer
[CODE]...
How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7

im trying to let users login to an application i created in vb.net using the user table of the application's database in mysql i heard that The usual way to do this is to have just one MySQL user called "[my_app_name]" with the relevant permissions. Then my application uses it's own user table to control access to the application, and the one MySQL user to access the database.

I'm working on an application in VB.NET that has to connect to a MySQL database and FTP. How secure is it if I used it in an application that I gave to other people. E.g. if I was to let other people use this application would they be able to find out the MySQL and FTP connection details through intercepting packets or something like that? If that's the case how can I work round this? Also, part of my application is an uploader for users to upload files, is FTP secure for that or are there better alternatives ways in doing that? My server is a Windows Server 08 if that makes any difference.

I hope someone can help. I was "volunteered" to come up with an application for a local charity group. What they are looking for is a system that will track[code]...
They picked me to help as I have done some computer work and for them that means I'm an expert.What they want is for me to use a Visual Basic front-end talking to MySQL. I know enough to realize that most systems DON'T work out first time and the chances are even less if that person (Me) has not much experience.

I would really like to know if there is anyway in which I can package two or more set up files together with my vb.net application; so that after installing the application, it automatically starts installing the other applications from the other set-up files.
In my case I want to include mysql server and client together with the application for a demo cd, that am making for a client.

I'm Using Visual Studio 2005 and Mysql Database to create a windows application. The datagrid displays all the records. Since I don't know how to directly update from datagrid, thats why I have used textboxes for the respective datagrid fields. A load button is provided which on clicking puts the data on the respective textboxes. The data can be edited in the textbox. Problem is that I can't save this edited or modified data back into dattabase.

I'm working on a MySQL database with a VB.NET front end, and I'd like the installer to first install MySQL and Connector/.NET (if they aren't already installed) and then run a query to load the dump file that I'm including among the program resources.Is this possible, or will I have to instruct my users how to install MySQL and Connector/.NET themselves beforehand?

Working on a project trying to use mysql and Visual Studio C++ 2010. I have an established connection to the database on a server using a connection string. My issue is I am not sure how to get the retrieved data displayed in dataGridView. Below is where I have my code for the button named Search. Right now all I am trying to do is get already inserted information out and displayed. Not sure if I am utilizing the dataGridView correctly or if there is another way. When I select bind to database I do not show any data sources even though in my server explorer window I show that I am connected. I have googled my eyes out and still havent found any information relating to a non console application. Here is some code that worked and returned a value of 1 to a textbox just stating that it had no errors in the execution. [code]

Using: VB 2008 Express?I created an application that connects to my MySQL, and everything works fine, but...
1. On my development computer, Windows 7, 64bit, I add the MySQL.data.dll file as a reference. I publish the program, run the setup.exe, and sucess.
2. I then copy my published folder to my test computer, Windows Vista 32 bit, and upon running the setup, the program fails to work because it cannot find the Mysql reference.
3. I then transfer my entire project over to my Vista computer, publish the program, run the setup.exe, and sucess.
4. I finally found out what was happening. My Windows 7 comptuer was not including MySql.Data.dll.deploy file in the Application Files published directory; but when I compiled it on the Vista machine this MySql.Data.dll.deploy was included.
So, in the end, I cannot compile the program on Windows 7, because it fails to create the .deploy file, and use it on Vista or XP (for some reason Win7 doesn't need this .deploy file?); but I can publish it on the Vista machine and install it fine on Windows 7, Vista, or XP. My targe CPU setting is Any computer.

I am building a database application using MYSQL as the backend. The MYSQL instance will be installed remotely on a share host. I have access to SSL certificates. I'm obviously not looking for any code but, conceptually, how do I go about securing the connection using SSL between my application and the remote MYSQL database?

I am developing a chat application using online connection to a mysql databbase. But i am facing a problem. After 10 minutes, MySQL closes all the chat connections because of the 600 seconds timeout (has been set by the host service i am using). I don't understand why is that happening cause every piece of my code which needs data from the database opens and closes the connection (i mean that it dosn't maintain the connection after the query's execution). If i .close() and .dispose() the connection, it still appears in mysql at sleep mode (it terminates only if i exit the program).

MySQL databases exists for saving values as strings (text only). Is there any way that i could store files with the same speed as a mysql command ? I know that it depends on the file size but lets say that the file is "Avatar.jpg" 50KB... I ve tried FTP but this is not what im looking for. e.g. You want your users been able to upload a file like the [Add This Attachment] button does in dreamincode.net and you dont have any background on PHP/HTML/Javascript/ASP.NET just VB.NET and the basics of MySQL plus you dont want to use it for a website. How do you accomplish this? Something silly that ive tried was opening an image as text then update the mysql server with that text but it didnt work backwards after i wrote the text on the file and oppened it ...it said that the image was corrupted.
