View 3 RepliesAm i correct when i say that at the end of the day a database can be built with a simple file stream and some logic to organize the data inside this big file??
View 6 RepliesI am really stugling with this an was hoping that someone has done this in the past and can lend some guidance, I have had a look on Google but I only seem to find examples of one parent and one child.Anyway back to the problem, I have a treeview on a form and I want to allow the user to create a tree structure of their choice. What I mean by that is no limit to parent and child combinations, so basically have the same functionality as in Window Explorer.Now comes the problem, what I want to be able to do is store this tree view hierarchy in a database, so that when they add a new node to the treeview it is stored in the database at the correct level. Then if the user closes the form and re-opens it loads the treeview hierarchy from the database.

Trying to build a front end for a new database I built at work, and I am having a problem.
This code is supposed to try to add a new customer to the database...in the
"btnSaveCustomerToDatabase_Click" VStudio is throwing "Reference to a non shared member
requires an object reference" but I am not seeing it.[code...]
I'm a Quite new to Visual Basic 2008. I have to build a database application for one of my assignments and one of the problems I'm having is to build a form that will be used to search a customer from a Customers table. The database is from access2007.
I have to have 4 radio buttons on the form which will be the options to search the customer by, so I can search by Customer ID, Customer Name, City and postcode. When I select one of those options I need to enter the phrase I'm looking for within a text box I have called TextBoxSearch then press a command button to perform that search but I'm not sure how to do this.
The customer ID is the 1st row, Customer name is the 3rd row, City is the 4th row and the postcode is the 5th row. How do i tell the program to go to that row and grab the detials based on the text entered from the text box? and display only those detials on the datagrid view?

I have a past experience with visual Foxpro and SQL. Now, I need to build a database with multiple data files (say 100 files), each data file with millions of records, each record with dozens of fields.Then, each data file is linked with other files by using different fields. Primary data is in English. Then there would be a translation of the English data is in another language. Primary data in English is stored in separate files whereas the translated data is stored in separate data files.
View 4 RepliesI am creating a Library Cataloging program for a local charity using Visual Basic.I have built the basic data table into the VB Project and I would like to populate it with the existing data that I have in the excel sheet containing the current catalogue. There are approximately 1000 records to import and I don't fancy inputing them by hand so I was wondering if anyone knows an easy way of porting the data across.

View 3 RepliesI am trying to create a button on a form that will open a connection to a database and list all the tables in the database inside a listbox. Everything I have read indicates I can associate a single table to a form, and have no idea how to:
a. Create code for the button to access all the tables in the database.
b. Display that list in a list box.

I'm trying to build an application to monitor a site to build statistics from the data being read. This HTML looks like this.
<div id="history">

Now I can read the html and put the text anywhere, I just don't how to read specific parts so I can separate the data out.
I have a Form with a Media Player in it. Which plays a Song.

It's playing in the background since the Form is hidden. When I play itin Debug, everything works fine. When I run the app outside Debug, I get this error: [URL] The Music File is there, but strangely, there comes this weird error.
A particular VB.NET project is actually throwing 'Build Failed' But when I try rebuilding again it says 'Rebuild Succeeded'. It keeps alternating this behavior. Kind of random. Any vbc.exe issue of long locking the PDB or xml files?
View 9 RepliesI have a vb.net 2008 windows form application that I was just assigned to work on. how to maintain and test changes to both the pre build and the post build events? Can you tell me how to test these events? My postbuild event, I believe calls a project file in the solution file that wraps files together in a bundle in debug mode. Can you tell me how the posbuild event works and when it is called?
View 2 RepliesI am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?
I just created a simple application. I Builded that using build->build myapp. I got .exe of that application. i runned. all went fine. but when i closed that app, even after closing it is in memory. it is still running. how to deploy it properly?
View 12 RepliesI have some very simple questions about making a release build exe in vb.net using MS VB 2010 Express.
I realize that my project's executable is built in the bin/debug folder. However, when I copy this to any other location on my computer or someone else's, this executable does not function. I have read that I need to create a release build but in MS VB 2010 Express, when I use the Project-Properties menu and change the Compile tab configuration to Release and the path to binRelease, I still get the exe in the binDebug folder and not the binRelease folder.
1) Is it normal that exe's from the debug folder do not function outside of the debug folder?
2) Most importantly, if the release build produces a faster exe, could someone please explain step by step how to do this with MS VB 2010 Express ? I do not see any button on the compile tab in the project properties that actually builds the release.
I was able to build both debug and release versions of my VB code before now I no longer have the option to build a release version. How do I turn it back on
View 3 RepliesSo when i build or click debug on my program. No errors come up and its smooth. So i decide to publish my programme. However. I come up with a bunch of errors during the publishing.
Here they are:Error 1 Cannot publish because a project failed to build. 1 1 Simple CALC
Error 2 Unable to copy file "binReleaseSimple CALC.exe.manifest" to "binReleaseapp.publishApplication FilesSimple CALC_1_0_0_0Simple CALC.exe.manifest". The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.
I have asked this elsewhere, but have never found anyone knows how to build an add-in for VBA IDE using VB.NET. Is it even possible? Could someone point me to an example?
