IDE :: Why Would Database Drivers Work In Development Environment
May 12, 2009
Why would database drivers work in the development environment of VB.Net and not once the project is built and installed on the same pc? I've tried the MS ODBC Oracle driver. I've tried various ODBC datasources. All work when I am in the development environment but none once I build and install. No matter whether the configuration is Debug or Release. This is the only project having this problem. I have other apps (VB.Net) that access the same database (Oracle 9.2) with no problem.The environment variables are the same during both types of runs. The error messages vary depending upon the driver being used.
how to run a Windows application within the VB.NET development environment. How can I 'build' or save my VB.net application, so I and others can run this application without runing the Visudal Studio?
I'm from an AS/400 (iSeries) background and have no idea about how a team of programmers work within the .Net environment. Lets say a company purchases a new button control. Now, in that company they'll have 5 or 10 developers working with that new control. Its my understanding that even if the control is in the GAC, it must still be copied locally to work on at design-time. My question is, what is locally? Does each developer have a copy on their own PC or is it held centrally on a server?
I work for a medical devices company and as such, we need to keep a very strict and regulated development environment.Since we are using MS Visual Studio as our main SW development tool we need it to comply with FDA regulations.So, is Visual Studio (and its compiler) FDA approved?
I have inherited a large VB.NET solution that was created in VS 2003. I am trying to update it to VS 2008 to maintain it. I no longer have access to an install of VS 2003.
The solution contains 15 projects that are console applications and 1 that is a Website application. The website application refers to some assemblies in the other console projects.
When I try to open the solution in VS 2008 all the console applications open but as it tried to open the Web application (or website? -- not sure) I see the dialog "Trying to open http://dmedibiz/dotcom.vbproj". It is unsuccessful in doing so. I don't have a website named http://dmedibiz on my development machine.
I tried changing the name of the website in DotCom.vbproj.webinfo, but that does not have any effect in VS 2008. When I go so far as to change the Hosts file so that the local machine resolves "dmedibiz" to the proper folder on my local machine, I keep getting prompted for a login and cannot access the folder even using the administrator login. I have tried adjusting the security on the Folder and in IIS Manager and even in the Frontpage Extensions, but nothing works.
So, what can I do to open this web project along with the other projects whose classes it references? Is there a way to change the website reference in the upgraded application? I actually do not want Frontpage Extensions in the site, but there was some reference to that also in the erro messages about installing them to "fix" the problem.
Here is the error I am receiving...
Unable to open the Web site '[URL]. Could not find a Web server at 'http://dmedibiz'. check to make sure that the Web server name is valid ...'
Can anyone tell me how to change the website location reference? Or must I remove the Web project from the solution and create a new Website and then copy in the files that need to be worked on?
In VS2005, I noticed that when you go from the code window to the form window, the form immediately appears, but then redraws again, and takes about 4-5 seconds to come back. Is there any way around this annoyance? Has it been fixed in VS2008? In general, has anyone noticed any speed improvements in the development environment between VS2005 and VS2008?
Well I've finally decided to upgrade some of my vb6 applications. Anyway I have two forms that are very similar one is customers one is vehicles. One of them is working on form load and one of them isn't. The one that isn't working I've traced the point it stops down to where there is a green line left of the code on the left bar of the development environment. This green line doesn't exist on the form that works. What the green line in this photo means? [URL].
Bigger Picture [URL]. I found a page that says the green simply means the code was saved but it's only on the form that stops working right after the execution of the sql statement. For some reason while stepping through the code it returns to the show command that was called to originally open the form right before the form opens but it skips everything with the green line next to it. I went and disabled tracking and it went away.
I have just started using VB.net, and am currently using VB2010 Express. Previously in VB6, I used the MSCOMM control for communicating via the serial port.
1) What is the minimum development environment required for RS232 communication? I assume VB2010 Express will not be sufficient.
Is it possible to use a JDBC connection in a VB.net application? I am unable to find any example code in order to connect to an Oracle Database using JDBC within .net without the need to use Oracles .net drivers (they seem to not work without the Oracle client being installed and thats a licence problem)
I don't THINK it should be a credentials issue.I'm reading the credentials out of a database and using the same ones whether the program is running on my development machine (Win7) or my production server (Win 2008 R2).[code]
I have an app that I'm debugging and I need to pause it by clicking on a "pause" button in the development environment. I don't want to stop it programmatically, just manually to check what it is doing. I know this should be simple but I can't find a pause button anywhere on the toolbar.
i made this thread and faraz zone made a guide for me, I keep doing the guide but i keep getting this error: url...untill now, now i end up reformatting my notebook and i try to do again Faraz Zone guide and i still keep getting that error, now I decided to make this new Question/ Thread.I already made my vb.net project using Microsoft Visual Studio 2010 that has database and multiple forms, and I already installed SQL Server 2008 R2. I want my project to be remote/network using lan environment, in what way i can do this?
for my vb project, i have to develop a system for a network environment. it means a central database to the application. i don't know how to do that. i am hoping to do a sql database. guyz please help me to do this.if you have any tutorials or any of your advices, will help me a lot.
I just created my first VB.net project using Microsoft Visual Studio 2010 that has database(.mdf) and some forms?I want my project to be remote/network using lan environment, in what way i can do this?i keep goggling i can't find the answer so i end up in your site, I already install SQL Server 2008 R2 in my PC, and i already set up 2 computer here in my house 1 act as a server and the other is client using Lan.
I have an application written in ASP.NET and using EF. I want to make a copy of the live database, have my application point to the copy, and be able to run the application against it as if it is live...but making updates to the copy.
I know I can manually copy the database and manually update the web.config files...but I'm wondering if there is a better, more automated method for achieving this with VS 2010?
Also, if there is anything I need to know about setting up a live/dev version of a database while using EF4.
I already made a project using Visual Studio 2010 (Visual Basic) and my database connected to SQL Server 2008 R2, also set up a PC 1 act as a server and the other is client i set this up for beta test.
I'm having issue about putting an IP Address to the server pc, actually if the IP setting of the server pc "Obtain IP Address automatically", i can open my application in the client pc, but once i put IP Address on the server PC i cannot open/run my application to the client pc, i cant figure it out how can i fixed this issue.
I have a WPF application that uses a SQL2008 database. I have a copy of the database on a laptop and on my home machine. My application is versioned using SVN and I am obviously able go from the work laptop to the home machine and update/commit as required to ensure I am using the latest code for the application.However the database is a different story in that any change I make I create a backup and then transfer the backup to the other machine etc. This way I get the data and the changes made on each system. In order to do this the database connection using a different connectionstring and I change a setting in my app to use a different connection based on my location.
I have now started to use LINQ to SQL and DBML files in my application, and finally getting to the question, I don't know how I can change the connectionstring it uses in code so it will use the correct database in the DBML.Also, is there a better way to transfer the database so I don't need to do the backups and restores? The only reason why I have not versioned the Schema is because I am not sure how that would handle my data as this is key to my development, ie various environment settings etc are stored in the DB and brought through at runtime.
I have VB6 Dll which I am referencing in vb.net ,I am calling the following function in it. It working fine in developemnt environment but not in deployement environment.
Error Method not found: 'Boolean MyUtils._MyUtils.LoadMyObjectRecords(ADODB.Stream ByRef, System.Array ByRef)'.
I need to create an application that detects the Installed andNot-Installed names of drivers in a computer. How to make this? Does this make easier to identify the Not-Installed drivers?
Followup to a previous post: It's been determined that Windows Device Drivers cannot be written in VB.NET; that's being dealt with separately.
What I'm interested to know here is if there's a DotNET Framework facility for adding/removing/managing device drivers; for example, can I build a VB.NET application to list loaded drivers, or drivers attached to a specific device, then load or unload those drivers as needed? It never hurts to try. In a worst case scenario, you'll learn from it.
At this time I am using VBScript to drive files thru a printer driver. Each file has to be ran at all the different preferences the drivers can offer. (papersize, dpi, simplex/duplex, etc.). I am developing a VB application and I want to drive the files with the app. I want to make setting changes with my app. and then set the driver accordingly and run the files. When I finish I want to dynamiclly change the settings and then run the files again. Until I have driven them with all the different settings.
I am creating a small application for my tech support department to remove a printer and it's driver. I can stop the printer spooler service and delete files related to these printer but, I can't delete the printer from printers and faxes window. I can run printui command to delete the printer in command window but in shell line the double qoutations are giving me problem.
i am trying to redistribute my app that uses Oracle 11g:
Imports Oracle.DataAccess.Client
The problem i am having is that it will not run on a machine that doesnt seem to have the correct drivers that its looking for. When i install ODAC 11.2 Release 3 (11.2.0.2.1) with Oracle Developer Tools for Visual Studio on the test VM it works just fine but thats a 230+mb file to download and install! Not to mention that if the user already has Oracle 10/11g on their machine that it may mess up their current connections/etc by installing that setup file.Is there another setup package that i can install that only has the Oracle Data Provider for .NET 2.0 11.2.0.2.0 or whatever its needing from that ODAC 11.2 Release 3 file.
I want to start a new project, an application to detect drivers installed and not installed. can someone give me some details about how can be checked, what codes i need to retrieve.
I own a small tobacco store and am trying to write a VB program to take a scan of the barcode of a Drivers License and extract, and display the name, address, age, etc for added security of my clerks and making sure we do not sell to minors.
The following is the code i have thus far.
Imports System.Text.RegularExpressions Imports System.IO Public Class Form1
I have some code to list all the print drivers currently installed on a system and code to change the default printer, does anyone know how this can be modified to delete a printer (eg: populate the listbox with installed drivers and delete the driver if double-clicked?). I know how to handle the double-click event, I just need some help working out how to delete the driver.[code]
