Yes, you can convert it. What is your question?

Converting old ADO code might not be very efficient; rewriting it to use a .NET DataProvider would not be very hard.

Not sure if this is a language/age gap, but I think this post is mostly going to be considered a spam.
You have not explained the problem, and not shown the effort made by you. So try to explain and describe your situation here.

Those are not errors. They are warnings. All they are saying is that you declared these variables, may you set values for them, but never used the values anywhere.
Anyway, I copied your code into a new Windows Forms and compiled it. I didn't get the warnings you're talking about.
|
|
|
|
|
hi, this is a console app. so did your win forms project work, if so, then fine, can you send me the project, via e-mail to me as a zip, so then i can then rebuild the windows forms. just did not get any errors. and said it did not build, from my external drive. able to do this for me dave. marvin.
|
|
|
|
|
I didn't do anything special at all.
All I did was apparently what you did. Since you have a reference to "System.Windows.Forms" near the top of the code, that tells me you added a Module to a new Windows Forms project, and then added your code to the new Module. You then changed the project Startup to either "Sub Main" or "Module1" in the Project Properties.
Again, those are not errors. Everything you posted is a Warning and will not, by default, prevent your code from compiling and running. Unless, of course, you turned on the option that says "Treat warnings as errors".
|
|
|
|
|
hi. so can you e-mail me privately and help me out, then i can then e-mail you back and forth. so, then how to fix this and my screen reader jaws says build failed. no, did not turn any thing on. so, how to fix this, and then get this to build. it is a console app. unless try creating a new console app, then maybe not add the windows forms. can you help. thanks.
|
|
|
|
|
I told you exactly what I did you recreate your project. You can go through the exact same steps to do it yourself. It'll take you 2 minutes.
Start with a new Windows Forms app, add a new Module file to it, and copy your exact code from your own post into that Module file.
Oh, and you're going to have to add a reference to System.Speech.
|
|
|
|
|
You need to be clear on what you are asking. And no, it is unlikely anyone will fix it for you and email you back all the fixed code. Unless you pay.

I tried to solve this and did not get it, the problem that I have a MatLab DLL file with a function looks like this
[tmin, mawp,sigma,tmin_c,tmin_l,segma_c,segma_l] = cylindrical(a,b,c,d,e,f)
I did reference the dll and the mwarray dll, when I call the MatLab's obj to the function it returns nothing, and if I use an index to map the array it gives an invalid index error. I am sorry if I didn't make myself clear, but I hope the code will.
This is VB.NET program that uses Matlab function to calculate some values, I tried to make the output as an array using ToArray function but it didn't work, Also in the MathWork documentation they talked about that conversion as in vb you need to use op_implicit function but I did not figure it out, I tried so many things but I am stuck here guys, appreciate your help.
'after importing dlls
Dim matlab As MAWP_CYL = New MAWP_CYL()
'this to matlab obj
Dim result = matlab.Cylindrical(1,1,1,1,1,1).ToArray()
'using any numbers for test
'here result have nothing when debugging,
the result has nothing, not an array or any form of lists.
|
|
|
|
|
What are the parameter values to the Cylindrical function supposed to be, and what result should it return?

Hello all.
Does anyone know how to send multiple latitudes & longitudes from VB.net to Google Maps and receive from Maps services what is the best route?
I'd like to receive something like this:
1) Address B
2) Address A
3) Address D
4) Address C
It would indicate me where to go first.
Thanks.
Paulo

Ah the old drunkards walk - I designed one of these in the 90s, for just one city. I'm betting Google does not have such a facility freely available, it is a MAJOR task to get right as you must take into account one way street and traffic conditions.

The API accepts multiple addresses, and returns the results in the form of arrays. The actual format to be used will depend on which version (iOS, Android, JSON) that you are using. The Google documentation should help.

I posted this C# board first which was a mistake again I apologize. I work for this company where the old programmer was in the process of rewrite the source code with no documentation at all from VB.Net to C# Now we have 4 programs total and they all update from the same database and get price updates on items. My problem is on one of the programs if a customer was to do full sync which is the whole database list of well 60,000 items I get OutOfMemoryException when it imports the last category Items. Here are the Exceptions Quote: Exception thrown: 'System.OutOfMemoryException' in System.Data.dll

Looks to me "it" is reading, updating and creating (Entity Framework) entities; but nowhere is it writing ("flushing") these entities to a database or garbage collecting. So, "memory" just fills up.
This may work for a few items (for whatever purpose), but not apparently for "60,000" (at one time).
For Each row In DataSetPricing.Items

What about using
XStreamingElement When reading the file
DataSetPricing.Items.BeginLoadData()
DataSetPricing.Items.DataSet.ReadXml(String.Format("{0}\Items.xml", My.Computer.FileSystem.SpecialDirectories.Temp), XmlReadMode.InferTypedSchema)
DataSetPricing.Items.EndLoadData()
BackgroundWorker.ReportProgress(60)
How do I change the code?
