I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

I have some items in my listbox which I will store everyone of them into my database, what I am doing now is looping the box and call my database saving logic to save every single item. I thought this is pretty inefficient, is there anyway that I can use to batch save my items so that I don't open and close the connection as many times as my items.
For Each item In outletToBox.Items
.CamCode = Items.ToString
.CamCampaignAutoID = retID
.CamRemarks = uitxtCamRemarks.Text.Trim
'---use savetable object to save to database table---

I have a scenario in my vb.net project.I have 70 textbox in my form and planing to save it in the database using access.It's hard to explain y is there 70 textbox there but i will just draw it here [code]5 in the column X 14 in row = 70 Textboxes.What i did is I place all the GRAVEL textbox in the table batch with the attribute name GRAVEL by using a string name called GravelLin.[code]I manage to save the text in this manner txtg,txt2g,txt3g,
1. Since the save data in my table in the database is separated by comma, I know how to extract it and place it in there designated textboxes, but im thinking, or my mistake, its a very long code.Is there a way i can make my code not that long??
2. Is there a better way to save my textboxes? in a way that my code will not that long.

searching a database using multiple words from a textbox showing in gridview.
<asp:TextBox ID="TextBox1" runat="server" Width="382px" AutoPostBack="True"></asp:TextBox>
<asp:Button ID="Button1" runat="server" style="height: 26px" Text="Button" />
[Code]....
It works fine, i click button and the gridview shows all the right records. The problem is when i use more then 1 word in textbox. it shows nothing. The record in the database field may have several words, so i need to search using all words in textbox.

I am working on getting a multiple values from a single column displayed in a single textbox or label. I know I should be able to find the information I need online, but I am coming up empty. I am using Visual Studio 2010 with SQL Server 2005. For example, I want to pull all the email addresses, that have a value, from a table and display them together. The output I am looking for is like this:

I have been looking all over the internet for the answer to this question: How do you save an Image (actually a Bitmap) to an ImageList at runtime? I have an extremely simple image editor that I created to make the images I require for another program. I have incorporated the image editor into the other program. However I cannot figure out how to save user-created images in the ImageList I am displaying via ListView. If I am aimed in the right direction, I can usually find my way through the maze.Additionally, I may need to know how to select that image (I may be able to figure this out later).

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I am creating a program which allows the user to add some buttons during runtime. Each button can be moved, sized and added to any tab on a tabcontrol. What I would really like to do is binary serialize a class that contains the properties of each button including which tab it's on.

This question is about VB.NET. I'm quite a novice on this one, so please forgive me if you feel that this question is nothing short of crazy or whatever. Anyway, I've been a creating a simple Windows addressbook Form application. We all know for a fact that a single person can have one or more addresses, of which a one-to-many relationship holds true. So there, my application also has to be able to edit each of these addresses (by the way, my application uses an Access Database, which really sucks but it's part of my task), and I already thought of using a control array (just like in PHP but it obviously never worked in .NET) for me to edit them. How am I supposed to implement this?

I have some questions on AppSettings. I can add a setting at design time from the settings tab of the My Project. I would like to add to the settings at run time. I have not found a way to do this. I would in VB6 use an ini file but would like to start using xml.
The .net makes this folder for the settings C:UsersRyanAppDataLocalTestAppSettingsAppSettings.vshost.exe_Url _0ay3fimqt4k0pp1s2e4vb3pi3iymxzx2 .
How do I retrieve the location to add to the xml file?

I want to place a few buttons on my form. The number is unknown at design time. Actually each button will represent an item entered in combo box. So if user adds an item, a button on the form should be added by the code.

I have added a DataGridViewComboBox to my DataGridView during design time. It has 0 items in it and I need to add a bunch of items to it during runtime.
In most controls, they have some kind of direct method like ".Items.Add("etc")", but for the life of me, I can't figure out how to access the DataGridViewColumn programmatically.
I can create a new ComboBox during runtime and add it to the DataGridView, but that's not what I need to do.
I played around with IntelliSense, I've searched on Google and I've looked through the documentation. The only thing I could find on MSDN was DataGridViewControlCollection, but I didn't see anything that would allow me to directly access that control.

I was writing a program for creation of form to ticket reservation. The form creation and everything is done a runtime. The problem is that i wanted to include a validation process in which the program will check whether user has entered the data(name) before showing select airline list box There are 2 if conditions which i both want to validate and if both the IFs are validated then i want it to show the list box.I dont know how to do that. Below is the code snippet
Private Sub button_selectair(ByVal sender As Object, ByVal e As System.EventArgs)
If Me.Controls.Contains(t1) Then
If (t1.Text.Length <= 3) Then
MessageBox.Show("please enter a proper name")

In the helpfiles of Visual Studio 2008 I read control arrays are no longer supported. There is an example for the new situation but then you need to hard code the names of all the controls beforehand.I do not know how many controls I need, could be one or 5000 (think simple image browser). Is it still possible to create something like that or should I change to a different programming language like Phyton? At the moment I work around it by using a browser control and then manipulate the <img> tags but I'm puzzeld as to why this functionality was removed and if there's a solution to the problem.Another thing I don't understand is where the app goes when it's installed with 'Click once'. It dissappears completely, doesn't show up in 'Program Files', can not be found by the search function but it *is* somewhere because you can start it form the Start menu. However, I use data which is in a subfolder of the program folder, which I nor my program can find any more after the app is installed. The program runs but it can't find any place to put/get its data so in the end it doesn't work.
I work around it by *not* installing the program but have people just run it after unpacking the downloaded folder. This works great but I wonder how long this will be the case until Microsoft disables this possibility? I have no idea why they would, but I also have no idea why they did remove the functionality I mentioned above. I already changed to PHP and MySQL because I had to throw away my carefully built W2K+MSAccess image database a few years ago and after installing Vista Visual Studio 2005 was a goner. OK, I upgraded but then no control arrays any more and now they hide the apps when you install them? Why on earth would they do that?

I have a basic IDE for a user control i am building. It allows me to add labels to a panel and move them around, like a very basic form designer. When I add the controls to the panel at runtime, I'd like to give the control a unique name string like how the VS IDE tracks the controls it already has and adds an extra number when it creates the default control name. I have tried checking the controls collection each time a new control is added, but wasnt sure if there was a good string comparison method to return a name with a unique number on the end that hasn't been used yet.

i am in runtime mode and have a form open. I do some calculations on it and based on those i generate some lines of VB code (concatenated and saved in a local variable). Is there a VB command that i can use that will take this code and INSERT it into another form?
i could copy the code, exit runtime, go to design mode and paste it into the form myself but because i want to do this for several subs for a lot of forms then it will become very time consuming.
