VS 2008 Which Controls To Use For Db View, Asp Alternative
Aug 8, 2009
I have a vb application ive been working on and its pretty much complete. I posted in the asp section but we couldn't get it figured out there so im reverting back to vb so looking for some help.I have a vb.net app I created and I have an internet browser embedded in it calling an asp page. the asp page is just a simple file that searches an access database. I used the asp page because I wanted to display the results with graphics and tables so I used html for that.Everything technically works except I am running it on a local intranet and the asp file is located on a server that is REALLY slow so it is taking 20-30 seconds to get my results. so, my question is, Are there any other options or ways I can do the search within the vb app itself so everything stays local and I don't have any speed issues. I can't install IIS on the local computer because the IT department is strict unfortunately.I don't HAVE to use "html" but I would like it to look nice with graphics and html was the only way I knew how to do that.

If I have the following ListView, how can I attach a SelectedIndexChanged event listener to the DropDownList so I can perform a command on the respective object? Imagine I have a list of new users and I want to add them to a usergroup by selecting the group from the DropDownList.
<asp:ListView ID="NewUsers" runat="server" DataSourceID="NewUsersSDS" DataKeyNames="ID">
<LayoutTemplate>

Im currently developing an app, in which there is a list box which will contain between 200 and 3000 items. These items are loaded into the list box from a .txt file. Now on the same form i have Picture boxes x 6 Textboxes x 5..The contents of which changes with each list item selected, and to do this i have the code attached to the list box, heres a snippet of the [code] but at the moment with 178 items on the list the total code is pretty big, and i get the feeling it would run faster if loaded dynamically.Am i right in thinking that? Especially when the list has 3000 items, thats alot of code to have attached to a listbox.And how do i go about making the code dynamic, im looking round the forum and seeing ADO database mentioned alot and that seems to be the answer at least for the text fields, would that also work for the picture box fields?

I'm writing an app that reads zip files from a folder and then displays them in a listbox. As a user clicks on one of the zip files in the list they can see a particular file that is located inside the zip archive in a textbox. The way I'm doing this now is to read the files from the folder and store the zip file name and the file associated with it into a two dimensional array. Kind of like this:
Dim a_files(500, 1) a_files(0,0) = name of zip file in folder a_files(0,1) = name of a particular file in the zip file The problem is that there may be more than 500 files so the array has to be scalable. I know you can use 'ReDim Preserve' to resize the right element on the fly, but I need to resize the left element. I've looked at collections, but I can't see an example where they can be multidimensional. Does someone know of an alternative way to store these values that would have the flexibility I need?

On our intranet website, I need to give option to user to specify the location where they would like to save files. The files would be generated by a background process. Is there a way user can specify the location? I can not use FileUpload since that requires file to be specified. I notice that FolderBrowserDialog is for clientserver vb.net app and not asp.net.

I have to turn this program in TOMORROW! I can't seem to figure out how to do this section. If someone I can do the second part.I have two text files, one is a single dimensional array, and one is a two dimensional array. One titled "Months.txt" and the other "Rain.txt".The problem is I have to read those into an array, and then after that, use a query to pull the information and display it into a data grid view style box.The problem I'm facing is when I pull the "Months.txt" text file, which has the months in order from January....December, and try to display it in the data grid it puts the length of the names of the months, not the actual months. me on this matter? I've tried to no avail. Also, how would you add all of the numbers in a single row of a two-dimensional array to give a total to display in the data grid? Also, the column?

Well this listbox contains sensitive data not very important but i dont want the end user to be able to see what the listbox contains, therefore i have hidden the listbox But my question is how do i store this information i could easily write it to a text file i know but the user could locate the text file. So i attempted to create my text file as a resource and that failed as i can read from it i cant write to it. More simplistic question. I have data i need to save from a listbox but if i save it as a text file the user could still access it and i dont want the user to be able to acesss the file i would like it to be internal because i also dont want the user to be able to delete the file?

I am about dead certain that in VB Express 2008 that I was able to have multiple tabs. And, on each tab I put controls. I could also click on a tab and see the controls only on that tab.I am now in Visual Studio Pro and I cannot for the life of me look at what is on a specific tab. Only the first tab wants to shows its controls.Does anyone know how to enable the environment to allow me to view the controls on different tabs?!

I've made an alternative to the MdiWindowListItem for window navigation in an MDI application. It consists of each window being added as a toolstripbutton to a toolbar, similarly to the Windows taskbar. I don't use any of the mechanics I should probably use, such as for loops catching each child window etc etc. Instead I look at window titles and do a lot of string manipulation and using counters etc.
I'd like to get rid of my method and use something a little more technical. I'd like to have the same effect, but to be able to add toolbar buttons relative to the MDI children as opposed to looking at window titles and such, because I've also got a plugin system that allows users to create their own windows and add them as mdi children. But, if a plugin is added, it doesn't get added to my toolbar taskbar thing because the titles are all user defined and I cannot control them.
So, basically, I want something exactly like the menubar's MdiWindowListItem feature, but using my toolbar idea. I want all MDI children to show up in it, including the 3rd party windows.

I'm trying to fill a ListView control in a VB2005 project. It works fine from underpinning (Access) database IF all the data is present. However, if a field is blank (in this case - a field called "Actual Date" which is meant to be blank for this record), the ListView will stop populating at that point.I thought this may have been the 'CausesValidation' property of the ListView but that doesn't seem to change the behaviour.Is this an inherent feature of the ListView - if so it seems daft - or is there a property I need to change or an override that I need to code?

figure out a way to link datagridviews to other controls like a combobox, list view or even another datagridviewBecause much of the code is managed by the IDE, I was expecting an IDE approach to linking controls. Is this the case or do I have to modify the generated code to do what I want.An example would be to use a combobox to limit the number of entries in a datagridview etc

I am rather irritated at this. I have no clue why looping through controls on a form and in groupboxes leaves out 75% of the controls.
Here's the code I have:
Dim settings As String = ""
Dim gbControl As Control
Dim gbbox As Control
[Code]....
I want to have setting save all settings to an ini file, and not have to reprogram the saving routine when I add a group box or control. At random times, any number of controls can be disabled, checkboxes can be checked and unchecked, radiobuttons can be checked and unchecked. Regardless of the state of the control, I want the control to show up in the loop. But they don't. Only controls that are enabled and only checkboxes that are checked, every other control state is ignored. That's crap, and is definitely not what is needed by any programmer of any type. We're capable of determining if a control is enabled, hidden, checked, visible, and otherwise.
How do I get the controls to be included in the loop regardless of their state?

I have been working on an app that was basically a vb6 app but had to be changed and I did it all using VB 2008. works well, great. One of the problems that I had was to work on different groupboxes or frames. Since they are layered on top of each other, working on one frame would mess up the others. Eventually it all went okay. but now if i want to add another item in the menu and hence add another groupbox (or frame) in the same app - it would definitely be a nightmare.

I've created an app (VB.NET) where each installation of the app works with a single local database on the PC. No multiuser and no ability for the user to change databases - the database is effectively part of the app, with a fixed scema, only the data will change.At the moment the database is SQL CE. It has about 30 tables with some simple relationships between the tables.
I'm wondering if there is an alternative to SQL CE that might be faster in this scenario. Although SQL CE is excellent and easy to use, I get the feeling there is perhaps an unecessary overhead when using it for something simple - and it does seem a little slow when my app is doing complex stuff that interacts a lot with the DB. In my prototype I actually loaded the 'database' tables from text files into Arrays and developed subs and functions to perform the database searches etc. It was blindingly fast but I realised it wasn't a scaleable solution because it was an 'in-memory' database. A compromise would be to 'page' data into array when needed, but it all gets horribly complex and that's probably why some very clver people have created SQL CE !

Using VB.net, I have a namespace which I'd like to rename for the future. However, I'd also like to keep the old obsolete namespace for a time to ensure backward-compatibility for our consumers for awhile. Is there a way in .NET to have two namespaces, one ordinary and one that merely is an alternative name for the other?

Below is the code for a linked list search I have tried to implement in to searching through each of the elements of htmlelements .For some reason If element.InnerText = (item) will only work if if is only a string ("example") .Are there any other ways of Implementing the for each loop to search through my item linked list?
Original code for searching for 1 string
Private Sub block()
Dim elements As HtmlElementCollection = webBrowser.document.All
Dim word_found As Boolean
word_found = False
[CODE]...
This is the Loop for item I have tried to implement but is not working ,because of the for each loop .The value of element.Innertext = "" or null when I try to use one of the linked list item[If element.InnerText = (item)] is used and only have a value when a string is used to [If element.InnerText = (google)]
Private Sub block()
Dim elements As HtmlElementCollection = webBrowser.document.All
Dim word_found As Boolean
word_found = False
Dim item As LinkedListItem = words.Head
[CODE]...
