How do you change an ADODB recordset to ADO.Net recordset?
View 4 RepliesI am calling a Fortran DLL from Vb.Net. I am declaring this in the class and then I am calling the DLL. I made this Fortran DLL from a Fortran Exe code. If I just use the exe code of the Fortran program I get different values than if I use Fortran DLL. First I thought may be there is a delay, so I used Sleep() before the end of the loop. But this does not change the values I am getting. I don;t understand why the results are different in exe and DLL, since I made DLL using the same exe code. I am not sure if the DLL is completely exited before it called again. Below is the code (partial).

I have a bunch of old VB.NET code, written originally on VS2005, and now I no longer have the license. I downloaded VS2010 free edition, and I just want to apply a relatively minor patch to an assembly/DLL. This particular DLL is being used by an existing Windows service (also written in VB.NET), and it's the server side implementation of a TCP remoting implementation.
So I need my patched code to be compatible with it all of this. When I naively tried to just build under VS2010, drop the DLL in place, and restart the service, it bails with some error about bad magic number or something. (I'm assuming because it's .NET 3.0 and the .NET 2.0 runtime has no idea how to deal with that).
Sorry for the long lead up, but I'm hoping there's some way in VS to say, 'build this as a .NET 2.0 assembly'. If this isn't possible, what are my options?
I have a question specifically about getting the current cookies set to a particular visitor on an ASP.NET webpage. I understand you need to use Request.Cookies - and by default it returns a collection of all cookies set, as an HTTPCookieCollection. However, the MSDN documentation states that you do: Request.Cookies("Username") as an example, in order to fetch an individual cookie and then compare whether it is set, etc. All fine and dandy but why adding parentheses and a string does the type suddenly change to
HTTPCookie.
I understand HTTPCookie is for dealing with individual cookies and HTTPCookieCollection is for dealing with multiple cookies at a time for like iteration purposes, etc., but I don't understand when on the MSDN documentation it explicitly states that the Request.Cookies property (the Cookies property) is of type HTTPCookieCollection, and if you do what I explained it changes the type (I can see this from IntelliSense) and it does not state this happens in the MSDN documentation. I'm not asking about the MSDN documentation lol, but why this happens when adding the parentheses and a string denoting the cookie name. I'm still pretty new to Visual Basic. By the way, I'm doing this all in Visual Web Developer although using VB as the language of choice.
I am using 3 unbound DataGridView controls to display certain information. To load the information into those DGVs, I am pulling the information from an encrypted file, decrypting it, parsing the information, then trying to fill the DGVs with that information.

I am trying to retrieve the Attributes of a class's property specifically. So for example. Let's say I have a class called "Employee", and a custom attribute called CustomLabelAttribute with a string value. What would I need to do to retrieve the value of CustomLabelAttribute for Employee.FirstName specifically? I assume I will need to use reflection, but it's kind of new to me, and I've just recently started using it on any level.

I was able to create programs way back year 2006 specifically using VB6, however, the line of work that I've been to and currently in to is not related to programming at all. I was not able to constantly hone my programming skills and I wasn't able to adjust in today's latest updates. Now, step by step I am trying to rebuild myself. I would like to ask the guidance of all those experienced members here, if you may.

Are there any tools available for automatically formatting vb.net code - specifically for adding line breaks at a predefined line length? I'm working with a lot of code with long lines (thousands of lines), and manually reformatting it is quite time consuming. I've seen a number of tools for rearranging code into regions etc., but haven't found any that reformat with line breaks.
View 2 RepliesI have a combo box bound to a datasource. I need to change one combo box (of many) to order the items in descending order.I'm guessing I could order the collection in the dataset, but that will mean all my combo boxes will be reordered?
View 2 RepliesI have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.

I'm working on the exercise page 73 (VB 2010 in 24 hours). It's basically a form with 2 text boxes, 2 text labels and a command button. It's really simple and uses this loop to cycle through the items, and tell me the name of them in a Messagebox

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

I am using a .Net JavaScript implementation called Jurassic to run user-controlled scripts within my .Net 4 WPF application coded in VB.Net - C# answers are fine. The script engine runs on its own thread and provides an API for the script to interact with my application. This all works really nicely until a user executes a script that causes an infinite loop and takes out a core of the processor.
[Code]...
The reason I care about keeping the thread alive is because the user who wrote the script and the user who is running it may not be the same, and I want to keep the experience as smooth as possible the the user running the thread. There also might be legitimate situations in which a single JavaScript function would run for a long time and I do not want to kill that, I just want to stop being allowed to hog the resources.
Solutions that involve stopping the thread from slowing down the system but that still show high CPU usage are not preferable because I do not want the user to wrongly feel that the application is resource intensive.

I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.
