Deletes The Wrong Variable?
Jan 24, 2012I have two (2) variables in a textbox (L7B) and (D2B).
TextBox3.Text = (L7B) &
" " & (D2B)
I want to write over (L7B) without changing " " & (D2B).I have been using the TextBox3.Text.remove command with success however in this case there are just too many scenarios. (D2B) isn't the same number of characters so I would have to determine the number of characters to remove in each scenario.
To write over (L7B) I thought I would try TextBox3.Text.remove ((L7B)). To my amazement VB accepted this command but when I run it it removes " " & (D2B). How is it removing the wrong variable? I could understand if it didn't work at all, after all that's what I expected to start but to delete the wrong variable !! why?
Set To Cascade Updates / And Deletes?
Dec 16, 2009Just looking to keep application looking neat, One Form Parent / Child relation, set to cascade updates / and deletes. What I'm looking for is when the form loads the user enters some information for the parent (about 2 column out of 5), then I create a datarow with the information that I have. At this point before I actually send and update command, I would like to get the next scope identity for that datarow.
The reason is I also use that Identity as an Id number in this case a receipt number, and the user will enter detail data that is stored in the child, then calls the save function, this is when I intend to actually call the update to the database.
So the question is, Can I retrieve the scope identity for a datarow that only exist in the dataset without calling the update command and actually storing the data in the database? Or in my case creating my own auto index sub a better choice?
.net - Linq2sql Synchronized Rapid Deletes?
May 7, 2011I set up a test harness by checking for and then deleting records added to the db in the previous testing session, and then I test my recording adding code by adding back the same records.Interestingly this code works fine when there is a break in the debugger, but fails with a "duplicate key" exception when I let it run with no breaks, which leads me to believe there is some kind of concurrency issue.The basic metacode is as follows:
DoTest()
dim j as datacontext
dim recs = from myrecs in j.mythings select myrecs where myrecs.key="key1" or
myrecs.key = "key2"
[code]....
I've confirmed that I'm properly deleted the previous added records, and this works fine as does adding the new records when I have a break in the code before I hit the add records step. but without the break, it throws duplicate key exceptions in the "addrecordestomytable" method suggesting that it hasn't grabbed the current version of the table when it creates the new data context in addrecordstomytable, even though the records should have already been deleted.I've tried refreshing the table, but this doesn't seem to work either.Note backing database is ms sql server 10?

View 4 RepliesDelete A Row In DataGridView AND Database Deletes The Next Row After Last Selected Row
May 15, 2011I try to do a very simple job which is: Delete a row in dgv AND database! But now after three days I'm running out of steam
The problem is: I select on or more rows in dgv and push the del button. The sub zDelete starts working and at the end the selected row is gone and the row after my selection is gone too!?!? The deletion of the selected row was well done in dgv and database. But why is the next row in dgv only also disappeared??? After a restart of the form the missing row is back up again. And when I try to delete the last row it trows an exception error: System.IndexOutOfRangeException was unhandled
The code fragment is this:
'Delete all selected rows in dgv AND database!

Program Deletes Either A Single Folder Or Multiple
Feb 24, 2012So I have been working on this small project for a little while now Basically I need this program to be able to delete a single folder or multiple folder depending on the text in the textbox.So far, I can do the single file just fine, this is the code for that.[code]Simple as it sounds...I haven't figured it out...then again I am pretty new to VB, being I started programming in it literally 2 weeks ago.I am guessing that I have to set a variable for the textbox...which leads me to believe I need to use something other than a textbox to do this...I was thinking of using a DataGridView...I not sure how I would make it check if there is anything in a cell then delete it if there is.
View 13 RepliesRecord Deletes From Dataset On Form But Not From Database
Aug 28, 2010Frontend: Visual Basic.Net VS: VS 2010 .net Framework: 4.0 Backend: MySQL 5.0. Everything is working well, add/edit/save. I am using datasets to manipulate the database the forms are created by wizard and i drag and drop the details over the form. The Problem: I delete a record on the form, it disappears (it deletes it from dataset i think) but i go to the database it is still there also if i close the form and re-open it the records re-appear.
There is something i do but it raises an error, after deleting the records i hit the save button,the following comes up. Transaction has already been rolled back or is not pending after that the records are really deleted.
VS 2005 Compilation Error Deletes Properties?
Apr 2, 2009We were working with a VB.Net app that contains something like 2200 VB modules/forms/classes and got a not-uncommon error message when we went to compile it. (Didn't write down the exact message, but it's basically unable to copy an image file that's in use.)Problem, of course, is that not everybody got out of the app when we told them to. Like I said, not uncommon. (It's a shared app that runs from a server.)Now, the weird thing. After kicking the offenders out, when we recompiled the program the image, which we use on search buttons, was gone. The file was still there but all of the property settings that referenced it were gone. Looked into the Designer code & they were gone from there, too. Seems to me that a compiler should *mark* the code that won't compile, not delete it.Anyway, I only see two courses. Either we restore our app from a backup, losing all our changes, or we go thru all the forms (like I said, there are 2200 modules-not sure how many are forms, but it's a bunch) and manually replace the properties on all the search buttons. Either way it's going to cost us at least a day's work.

View 7 Replies.net - Visual Studio Loses/drops/deletes VB Continuation Lines After Subroutines?
Nov 20, 2009Several times while debugging a VB.Net program I have found that continuation lines are missing from a subroutine designed to handle an event. The continuation character "_" is there but the following line is missing
[Code]...
The first few times I figured I had made some editing error, but this has happened 3 times now, always in the same way (different subroutines but same place). As far as I can tell, no other continuation lines have changed. Is this a bug or some feature I have missed?
Create An Object Of A Class In Which There Are Properties And Functions That Do Database Selects, Updates And Deletes?
Oct 22, 2010how to implement UI, BL and DAL in a project the way that I see it as a requirement for some projects. The way I am able to do a project now is from a form create an object of a class in which there are properties and functions that do database selects, updates and deletes. Looks to me that doing a project like that is separating the UI from the DAL. In an update button click event I may call Obj. Delete (txtCustID.txt) for example. I don't understand the part of further breaking it down to include a Business layer; in which a vb solution is made up of three solutions.What goes in the BL?Does the BL call the DAL?

View 5 RepliesCreating And Using A C DLL For VB?
Jun 3, 2011I am trying to learn how to create a DLL in C (using Visual C++ 2010) for use in Visual Basic (2008 Express). I am a novice programmer, so please bear with me. My objective is to learn how to do starting with a very simple function, and I foundC++.html This examples presented in that tutorial are for Visual C++ 6 and VB6. I know there are differences between VB6 and VB2008, so maybe this is why I am running into problems following this example. In Visual C++, I created the DLL as a Win32 project. The function is simply summing two integers. I put the function "sum" in the source file "dllmain.cpp."

View 4 Replies.net - Creating A UDP Packet?
Mar 10, 2009I'm building a simple udp lan chat application in vb.net and I'm wondering how I should split my packets. Each sent packet should have like an id, a username and ip address from where it's coming and maybe also a command part for like join or leave to update my userlist and a text message. I'd like to know what is the easiest way to put all this in a simple packet then easily split and access different parts from it when it's received. thanks.I'm using UDP since this is only in lan so i'm broadcasting to *.*.*.255
What I want to know is what would be the most easy and powerful way to format my packets so they include a username , an id, a command and a text message, then the user receiving it decrypt it to show only the message written by which user or if it's a command like join or leave to show the appropriate message of joining and add the user to the list for exemple.
