1- I've a database access without password on the Server.I've created forms by vb.net to connect to database through OLedb Connection *like this
PHP
Dim Connec As New OleDbConnection("provider=microsoft.jet.oledb.4.0; data source = \Serverc$xDB.mdb;")
my problem is : I worte : if I want to connect to database from any pc I must save Username and password to control userpasswords2 (soted user name and password from User accounts)that's big problem , so I must save this to all client pc and the client can access Server system Drive there are no security ,this is the fifth day to find a way to connect to my database from server without share system drive.I tried to used it but not working.where can I write server name and path database and server's User-name and password.I've an exe file on server drive like this \Serverc$1.exe
I want some client to run this file with out share the file.If I can to creat a form by vb.net has a Username and password to run this exe without client know the userName and password.I'found map network , but is not ok for me.If I mapped network drive to client, then he can copy files and read some of security data.Is there a way to access this file from server without mapping or sharing folder for public ?

In businesslayer, there is a inherited Class Called BaseEdit which contains contractor and base properties. There are about 30 CustomEdit (inheriting classes), all of them has methods "Load","Save" and "Delete". The require for this existing system is to add a readonly user. Possible solutions considering the cost of works:
1) Modify the BaseEdit so all CustomEdit can stay the same. The system will check 'user role' in session by using httpcontext then to accept or reject the user's action.

Wondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.

what can I do to be able to install the app on a different computer which does not have .Net and does not have visual basic 2010 installed.

We have 3 databases providers we use to connect to our databases: DB2, MS SQL, and Interbase. I would like to create a single generic database wrapper class that can be used to talk to all three just by passing in the correct connection string, username, password, and the provider desired.
I don't want to have to add references and import all three providers in the database class. Is this possible?I have done this before in Java using the Class.forName() function.

My problem relates to executing an application located on a network share and getting various security exceptions in trying to do so. By far the greatest number of replies to this sort of problem relate to creating a new Code Group under Runtime Security Policy in the .NET Framework (v2 in this case) Configuration tool. However try as I might, and I've spent hours, trying various things with the config tool (and with caspol), I just cannot get my app to work.Still fails on things like reading command-line parameters and displaying a web page in a WebBrowser control or firing up a browser using Process.Start. In fact I've regressed to creating a VB6 version for this particular task as time is off the essence. Which works fine! As I mentioned lots of people have posted on this topic and not s few of them seem not to have resolved their issues either. So I was wondering if anyway had come up with a definitive solution for this problem which, in my case, seems to affect XP machines only? Seems to work OK on Vista, 7, 2003 Server, etc - although I haven't run exhaustive tests in these environments.

I developed a Visual Basic Program in my laptop. I can run the program form my C Drive and works perfectly.
Then I put the program in a Share Drive and:
1. If I run the program from my laptop but in the Share Drive I get this Error[url]...
2. If I run the program from my desktop and the Share Disk it is works perfectly.
3. If I run the program from a different user desktop and the Share Disk I get this error[url]...
I suppose it is a Security Issue or something like that but I am not totally sure and I do not know how to fixe it.

I've created an application (a simple calendar app w/vb.net) for my own use and would like to share it with you guys. I don't want money for it, just for the fun of sharing, and maybe get some feedback on it, not regarding the code, but the usability and concept.
However, this might not be the right place, as this forum is more about getting help on specific questions regarding code.
I've looked at codeproject.com, but it seems it's about presenting particular topics concerning code.
Does anyone know of a good place/forum to share and get feedback on finished applications?

I am wanting to expand my programming knowledge base and the only way I know to do that is to actually do stuff. I am wanting to write an application that performs common systems tasks from a single location. Just simple things like deleting text files, maybe displaying drive space, etc. In order to even begin to do this I have to understand more about the my.computer class in VB. Does anyone have some good info that breaks this class (and possibly related classes) down hierarchically? MSDN offers a lot of info but doesn't really give a lot in the way of explaining how certain classes are interrelated.

In VB.NET, my application is quite simple, and it accesses many images and creates a list with them.The images are in my application's Resources folder.The images are accessed in my code where I typed the path, in my PC, how to reach said folder.Works like a charm, my project displays the images etc.Now I go to Debug->Build.Now I go to the bin folder, release folder, and find my application. I upload it.I share the download to a friend.My question is, will the images my application should show will appear? Considering the path I created in the code was manually written?

I have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System

Any simple way of automatically updating a newer version of my application from a network share. Everything I have read pertains to an update from a web site. This is possibly a simple thing to do but as I have 6-8 users using the application I have to email them all stating there is a new version on the share and for them to copy and overwrite the existing application executable in the program filesapp directory. If this could be done on launching the program within the splash screen that would be fantastic.

I have data entries in my database that have a common field. For example:
account_id type user_id
1 new 1
2 old 3
3 new 1
4 old 1
I am using a query like this(mysql): SELECT account_id, type, user_id FROM table WHERE user_id = 1
This is just all theoretical. The problem that I am having with this is it is only returning the first result in this case account_id 1. How can I get it to find all the results with the user_id 1 because in the way I am thinking that it is failing is that it is finding only the first result and then ending?
