View 6 RepliesSql - Find Tables Used From A .net Application To Remove Unused Tables?
May 10, 2012We are presently developing an application, let's call it APP1, which uses a SQL Database which have about 800 stored procedures, 600 tables, etc. APP1 was originally created in order to replace another application, APP0, from which we do not have source code but only SQL tables, Stored Procedures, views, etc. Previous programers of APP1 used some DB objects from this same database and added some other objects specific to APP1 because it becomes bigger than APP0. And we do not need APP0 anymore as APP1 does all what we want, and more.
So, now, we are thinking about a way to find out which objects are used by APP1 in order to remove objects which are ONLY used by APP0.What is the best approach to discover all objects used by APP1 without having to open every single class and form?
Once we will have a complete list of these objects, it will be easy to use a program we bought which detects all dependencies for all SQL Objects specified directly from SQL and remove objects which do not return from any dependencies. Any ideas of how I could get this list without having to go through all our program that have many, many, many classes and forms?
Note : I know, in a perfect world, all calls to PSs and tables should be in a DAL but in the case of the application we're presently working on ... this is not our case! Yippy! (sarcastic yippy) ;)
Note 2 : This application is not using any ORM. So all queries are directly using SqlCommand. So any call to any DB objects are in string format.
After Converstion Of 6 With Label Arrays To 2010 Program Fails With Stack Overflow?
Jan 12, 2011Now I see that VB tells me that label arrays are no longer supported But I also see that VB2010 is providing the relevant logic to update each of the label array fields I was until today using VB2008, because after running this application it crashes with a report of stack overflow, I assume it is related to the label arrays, but have no idea. So I have upgraded to VB2010.
In VB2010, I note that the immediate window is reporting A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll Now I have used label arrays for showing columns of like data, generated by a for loop. What should I be using it its place, maybe a grid..
Remove A Null From A String?
Nov 4, 2009This should be simple but apparently it's not. I have a text file, 694 bytes. At byte 500 there's a null in the file. I've tried reading it as text and binary and I end up with a string, 694 bytes long. But anyting I do with this string fails because it appears to stop at character 500. I can do a ? asc(mystring.substring(549,1)) and I get 9 (tab). Print character 550 and I get 0. Print character 551 and I get 32 (space). How do I get rid of this null?

View 8 RepliesIdentify Unused DataSets In Project?
Sep 3, 2010I'm working on my first real vb.net project, after years of using VB6. I'm using Visual Studio 2008. While I've been learning, I've added lots of DataSets to my project and then realised I'd got something wrong, so I've added, and begun to use, a new one. Trouble is, I'm not sure now which ones are used and which aren't.
How can I identify which DataSets aren't being used, and then what is the best way to remove them cleanly? Or should I stop worrying about tidying up and get on with the development work? ;)

View 1 RepliesProgram Using Arrays And Functions - Highest / Lowest Number
Jun 14, 2012I am new to using VB2010 (and coding in general). Also brand new to these forums . Okay so I am making a program that: allows the user enter the number of customers served for each of 12 months into an array. The application should calculate and display the following statistics: total number of customers for the year, the average monthly number of customers, and the months with the highest and lowest numbers of customers. Use inputBox to get user input. Do not accept non-numeric or negative numbers.
The problem that I am having is that I do not know how to display which was the best and worst month. I imagine I need something that targets the highest/lowest number and finds the text in the corresponding index but I'm not sure how to do this.

.net - Windows API Leads To Different Results Based On Name Of Unused Variable?
Apr 5, 2012Everything I know about .Net programming tells me that the behavior I see here is completely impossible. Simple code:
Structure WKSTA_USER_INFO_1
Dim wkui1_username As Integer
Dim wkui1_logon_domain As Integer
[Code]....
When I put a break point in here, I see that after RtlMoveMemory, my wk1 contains a pointer to a username, and all the others are 0. This is consistant. Now, if I change Dim test As String = "" to Dim login As String = "" and run it again, wk1 contains pointers to both username and logon_domain.
If I change it to Dim login As String, it contains a pointer to only the username. Depending on what I change that (completely unused) variable name to, I get a different result.
I have always been under the impression that it cannot possibly matter what you choose to name your variable. And that declaring a variable, and then never using it, cannot possible be different from not having a variable there at all.
I've tried this on 2 computers, with consistant results (one on .Net 3.5 and one on 4.0). When I tried converting it to C#, however, I was not able to reproduce it.
I am aware, by the way, that I can just use System.Environment to get what I need about the current user information; this was old VB6 code that was automatically upgraded (and I've edited it a little to make it more trivial).
