VS 2008 Can Set Up A Series Of Calls At Application Load
Apr 15, 2009
I have a VB6 project that I'm converting to VB 2008. There is a routine in this project to LoadArrays.By passing the proc name and arrayName I want the info loaded into, I can set up a series of calls at application load and have these arrays available throughout the application (Info is used in many areas to populated controls)This routine makes use of Getrows.Example:arraydef = rs1.GetRows.This will load all fields and records into the array.Is there an equivalent in 2008?

I am venturing into WPF - first time in (VB).NET - and trying to re-create a project I started in MS Access VBA. It basically scrapes a series of pages within a web application. As you may have surmised I am having trouble with the LoadCompleted event.I have searched and found some information on it, but the "flow" of the code only lends itself to waiting for one page to load.url...All of the code execution is run in the DocumentLoaded event which works fine when you just need to navigate to one page and execute code. But I need to perform a series of these cycles for my application. How can I reliably wait for the document to fully load while still keeping the code execution in the same Sub AND not locking the UI thread? [code]That's it. Repeat for n times. my interactions with each DOM are significantly different.

What the Win32 API is? I have looked around but no where really outlines what it is. Is it basically a set of procedures, outlined by Microsoft for programmers in order to get services from the operating system? In essence is it the equivalent to making system calls abd and library calls in UNIX? And yes I now Windows makes library calls too.

I have been using DBTransaction for my current projects that access a single database. However, I read some documentation on TransactionScope and was wondering in which scenario would using TransactionScope be better? Or should I be replacing DbTransaction calls with calls to TransactionScope?

There is a very strange problem with a Windows Service I am working on that I would like to understand why it occurs. The service loops every 5 minutes and then within that loop it loops through keys containing webservice URLs that are numbered such as:
<add key="URL.1" value="http://dummy1.com/Service.asmx"/>
<add key="URL.2" value="http://dummy2.com/Service.asmx"/>
<add key="URL.3" value="http://dummy3.com/Service.asmx"/>
The code that does this check is:
If String.IsNullOrEmpty(AppSettings("OM." & intCount & ".Name").ToString) Then
When it hits a key that doesn't exist an exception is thrown and the service stops and waits for 5 minutes until the next loop.This usually works great but every week or two the Windows service will crash on that line without any Exception. The application log has a line from before that line but nothing after, none of the Try Catches are hit (the main one is catching the base "Exception" class).In the Event Log for Windows is the following:
Faulting application name: MyService.exe, version: 1.1.2.0, time stamp: 0x4fa22a24
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0xe053534f
[code]....
The weird part is that this line of code is executing fine 300 times a day for at least a week which is around 2000 times before that one time it causes a full crash of the application. why this is occurring? I have changed that line of code to not rely on Exceptions and it has been working fine for a week now with no crash so could be something to do with too many Exceptions - maybe causing a stack overflow?

I am working on an application that ties into a SQL database on the back end. Currently the main form contains a series of combo boxes (Graph type, data format, location, and customer), two date pickers, and a button to launch the selections in a new form. Everything works just fine except there are a couple of things I can't seem to accomplish.
Example Data:
[CODE]...........
Case Select (with commented out lines for variations attempted):
[CODE]..........
1) I would like to be able to use some sort of case statement to color the bars in my chart based on value. I have tried approaching this in a couple of different ways but neither of the options seem to work. First, I tried this (the If Not is used because depending on what values are passed to the stored procedure in SQL, different columns will be returned):
[CODE]..........
Only one series is created with this method, so I can see how/why a Select Case would set all bars the same color. I have also tried creating a series for each row in the returned dataset but it results in 22 bars of different colors, for each of the rows (484 bars):
[CODE]..........
So is there any way to modify the second set of code there to only select the value from the "Percent TMHB" cell that corresponds with Row(i), rather than ALL values from the "Percent TMHB" column for EACH Row(i)?
2) Since I am drawing/creating these graphs in a new window, is there any way to also create a new timer on the "newFrm" and have the tick refresh the data? I've struggled with this but I feel like it should be easy. Say someone chooses a "TMHB", "Percentage", "Chicago", "All" (Graph type, data format, location, customer) and launches the graph, which opens in a new window, then they want to do "TMHB", "Percentage", "LA", "All" and have both windows up, refreshing automatically throughout the day. Can I somehow store the SelectCommand.Parameters values in the new form/timer so that it will query the database again every 5 minutes?
Example code for the StoredProcedure and creating the new form:
If combo_GraphType.SelectedItem = "TMHB" Then
Dim newFrm As New Form
Dim newChart As New Chart
[CODE]..................

We have a client server application that 650 users are using everyday. Lately they have started complaining about over all slow responses and slowdowns in normal application usage like searching, reporting etc.We are using .NET Framework 3.5 and .NET Remoting is the technology we have used for client connection to the server side. We can't remove that and use something else due to legacy application maintenance. We are using SQL 2008 R2 x64 on a very good server.We have gone though the basic steps of making sure that all the SQL side is ok everything is well tuned but we need to convenience the client that it is not the application but the database that needs to be regularly maintained by a DBA in order for it to run smooth due to the nature of the application making tons of changes and inserts in the database everyday.
Anyways I need to write some sort of module that can plugin into the .NET Remoting calls so it can log the normal usage of different methods on the server like;* How many times a remoting method is called* What params a remoting method is called with* How much time it takes to execute each remoting callIs there anything available in .NET Framework that can help me? I read something about .NET Remoting Sync but not too sure if that is what I need to use? If any can shed any light on the subject or nudge me in a right direction with some sample code, that would be great.

Do we have nay .NET framework classes to replace the following API calls?
CreateWindowEx
GetWindowText
ShowWindow
SendMessage
GetWindowRect
Basically we have migrated our application from VB6 to .NET and used same API calls in .NET as well.
Now the time has come to replace all API calls to .NET framework classes.
We used those API calls to validate textboxes by popping up a temporary error message box next to textbox object. After few seconds, the error message box disappears by itself or on loosing the focus of textbox.
If we can use the similar functionality of .NET, then there will be less code changes

I have a thread in an application which calls a sub routine Main(). The Main sub routine in turn call several sub routines/functions from with the same module,several different classes in the same application. Also some sub routines/functions call routines from a class library. Now say the routine/function in class library goes into a infinite loop and never returns. I would like my thread in the application to raise a event and display message to the users about the infinite loop. I am giving some sample code for the application.

I am trying to run a fortran .exe in VB with the Shell() command. The fortran .exe, when ran, it asks you for a file name. It works perfectly on it's own, but when I try calling it through VB Shell(), it does not work.. (i.e. I cannot get VB to get the file name in it.)
Added info:I am using VB9 but I'm writing in compatibility to .NET. As for the Fortran .exe, when you call it, it opens a command window where it asks for a file name (which I got as a string in VB and I'm trying to pass it in), then you press Enter and it's done. Basically the .exe takes a text file and creates a new text file. We've also tried adding & mystring when calling the exe, but it gives a "file not found" error.

I have a problem I've been struggeling with for a full week now, and I'm not able to solve it by myself. I've been googeling, and searching in all kind of forums.I have found lots of "this might work", tried it, but no, no success. If anyone have any clue,I'v got, from an external source, lots of classes and functions written in VB that I need to be able to use from a C++ application. My first though was: no problem, I turn the VB code into a dll, and load it from my C++-program. This was though harder than I ever could imagine. My C++-program is not written in Visual Studio, but for simplicity I started with trying to load my VB dll (written in Visual Studio 2010) from a Visual Studio C++ application. This is my code so far:

I looked at the link with the tutorial, but there is a small problem: there are no such thing as "ActiveX DLL" to choose among all the project types. And yes, I do have Visual Studio 2010 Professional (a trial version, but still).

I want to able to hold a key down while the application is loading and depending on which is being held down a certain form is shown.
For example holding down shift and the opening itunes opens a little dialog allowing you set the library(or something)
I can check whether the shift/Ctrl/Alt are being held down but i'd prefer to use the letters/digits.
Such as hold 1 down to open Form1 and hold 2 down to open form 2.
