I have created a program who needs to connect to a mysql db with the mysql connector 6, and it works great, at least on my computer
If i build the app and puts it on another computer and tries to connect to the db it says it can't find the file who where referencing to MySQL.Data??
Shouldn't that reference dll follow with the program in the programs exe or something?
I Have a c++ program that is already completed but has no ineterface. So What I am trying to do is translate the c++ code over to Visual Basic, which is trickier than I thought. I need to browse for a text file, cross reference that with a csv file which will match IDs and replace in the text file, outputting to a textbox to save

View 1 RepliesI recently wrote a program that collects information from the network can displays it in a DGV for the user to see. I tested this on networks where I would end up with several thousand items brought back and all worked fine, very little memory increase and once the search had finished the memory usage went back to pretty much what it was before the search, so I assume I have no major memory leaks that I should be concerned about (I'm careful to always dispose of things and clear large variables where possible).
However, a new company has now started using my application and they have several hundred thousand items that my program will find. They reported that they leave the program running its search for a few hours and most of the time it crashes with an Out Of Memory exception. Now I did have my app do some caching of certain information to avoid querying the network more than was necessary so I thought well maybe this is what is causing it but I added an option to turn that off and they say it still happens. So the only thing I can see it being is simply the amount of data that the program is finding and having to store in memory.once my application has gathered information about the items it stores them in a List(Of MyItemClass) and then when the search is complete the items are added to the DGV. So I'm thinking maybe its just the size of this List(Of MyItemClass) that is simply getting too large. Bear in mind that each instance of MyItemClass in this List can have quite a lot of information in it as it has several properties that are List(Of String) that may contain a few thousand strings in some scenarios.How do you deal with such large amounts of data without running out of memory?I'm assuming the only option I have got is to 'page' some of the data to a temporary file on disk once I get over a certain number of items in the List(Of MyItemClass)?
I must have inadvertly messed up my data connection but not sure how to fix it. when I check the table adapters I can view data but when I load the app I get these errors and no data loads, how can I look at this log and make sense of how to fix this?

View 1 RepliesWhen I'm adding project reference to a project in VS2010, VS is unable to refer it in the project,
but when I'm adding the dll path (by browse), VS is getting the reference and project is working fine.
I'm using VS2010 professional edition and both the projects are in .NET Framework 4.0.
I am after the one which is most used. A number of ones I have come across are:

I'm a VBA programmer and can do Office integration in Office applications.I'm programming in VB in VSTS 2008 and following these steps to create an Excell application at runtime: [URL] but it is not working.The issue I'm having is when I add the reference, the library is not recognized by VBE intellisense and compiler, so: the code doesn't run.When I use late binding technique and declare variables as objects, the code runs OK, but I don't want that way.I tried adding the references in two different ways:
1 - Menu Project / Add Reference / tab COM / Microsoft Excel 11.0 Object Library / OK
2 - Menu Project / VB Properties / References / Add / Microsoft Excel 11.0 Object Library
Both methods didn't work.
I'm using Visual Studio 2010 and .NET3.5. I've created a WCF service application. I'm including two DLLs that contain the types I'm returning. The first method I wrote works both in WCF Test Client and also in a console application I created to test. When I move on to the next method that returns a generic list of a type. It works great in WCF Test Client, but when I update the service reference it acts as if the service is unavailable. All my objects say can't find reference, and I can no longer see it in the object browser. It's like it just disappears. I can still see it in the Service Reference folder. If I go back to the WCF app and comment out the contract and implementation of that one method it work again. I created a local class very similar to the class I'm using from the dll, and the it works. Is there something I'm missing here? Can someone point me in the right direction?

Just downloaded the connector/net from MySQL website, and after installing successfully, I am not able to add a reference to the .dll to continue using the namespaces to establish a connection to a Mysql database on my website.
I am trying to add a reference to a DLL written by a coworker to a project of mine but I am getting this message:
The referenced assembly "SomeDLL" could not be resolved because it has a dependency on "System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project.
I have an application that I have in VB Express Edition 2008. I have an MS Access database (Access 2003) that I have created a data reference to one of its tables. The table contains 3 fields ID (Counter), Name and Price (text and double). When my form loads I simply want to read each record in the table and create a variable with the same name as the product name and assign it a value the same as the price in the table. So, record 1 in my table has Prod1 in the name field and 2.59 in the price field. I would like these variables to be created when the form loads and be available until the user exits the form.
It seems simple but I cannot find reference to a similar situation anywhere I have looked.
In the Form_Load routine the following line was generated via the designer:
Me.PricerTableAdapter.Fill(Me.PTODataSet.Pricer) assist if possible.
I need to pass a reference of a class instance to a new form; the newform obtains data from the user to be added to the class instance. How might I do this? Is there a way to pass it as a parameter via the ShowDialog call?

I wrote a routine using a DatagridView that I dragged/dropped from the toolbar--populate it with data and it works great! Now, I need to reference the datagridview from another form. So, I (hopefully, naively, after the fact) declare a Public dgv in a module with the same name as the dgv in the form I'm trying to reference--in the form itself, dgv.rows.count = some number, but when I reference it outside the form I get errors. Obviously my public declaration is not working as hoped--the dgv was working within its form without the declaration so SOMEWHERE it is declared and is not public, but since I dragged/dropped it (i.e. did not instantiate in code).

Is there a way to change reference at runtime ? I am automating Word from VB.Net. I think what I have coded will be same for both Word2003 and Word2007. I used Word 12 Object Library reference(which is of Word2007). So, I want to know how to make it compatible with a machine installed with Office2003. That is, it will check the whether the machine has 2003 installed. If so, use that reference. Otherwise use 2007.
