VS 2008 Alternative To A 2 Dimensionable Array?
Jul 24, 2009I'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?
Alternative Than SendKeys To Change The Focus In The WebBrowser Control?
Mar 4, 2011At the moment I have this to change focus of an element:
SendKeys.Send("{TAB}")
Instead of using that I was wondering if I could do something like this:
WebBrowser1.Document.All("id").InvokeMember("click")
But to get focus to the next element in line, like the next one from the current focused item.
Vb6 Migration - .net Taking Too Much Time To Load User Control Containing Label Control Array?
Dec 22, 2011I am upgrading user control from vb6 to vb.net.In the vb6 application I am loading 3000 labels using a label control array.In vb.net I am doing same but it's taking too much time to load.In vb6 it's taking 1-2 seconds, but in vb.net it's taking 30-40 seconds for same work. Why does it take too much time in vb.net for same work?Code is given below, here Led is the label control array.

Auto-renumbering Control's Control Array?
Jun 21, 2010The situation is like this, says:I have textbox1 to textbox20 to show real-time reading, then textbox21 to textbox40 for other purpose. So textbox1-20 can be manage in group through: For index As Integer = 1 To 20 Form1.Controls("Textbox" & index).BackColor = SystemColors.Window Next The problem is, after some time i feel i like to change the order or add/delete few textbox, then i need to change the control name one by one by entering the name by hands(says if i add a text box then its name will be textbox41, then then For loop wont work, Or I deicided to delete the textbox15, forloop wont work either, then i need to rename them manually.)
Question: If there a ways that create a control array in VB 2008 express edition? which can set the name of Textbox1-20 to ButtonGroup then refer to them by says Buttongroup(1) for textbox1? (which means set a group of control in one name)
How To Find Out If A VB6 Control Is Indexed (control Array) In .NET
Dec 16, 2010I working on a VB.NET project to manipulate a VB6 form using COM Interop. Some of the controls on my VB6 form are indexed and some not, so calling ctl.Index fails on those that have no index. Is there a way to work out if a control is indexed?

The program does not crash or anything, but the picturebox is no where to be seen on the form. How to I make this work correctly?
And is 'Control Array' the correct term for this? or something else?
Get The Index Of A Control In A Control Array?
Dec 26, 2009I populated a form with several progress bars and added a function to handle a click event via AddHandler. The event fires and I have been able to do things with the control using the passed object 'sender', but I can't for the life of me determine what the index of the control is in the array.
Why is that important to me? Because I want to click the control, have a container of textboxes become visible, and populate them with data from the reference in my database based on what control was clicked, and update that data as needed. Making the container of textboxes visible, and even moving it based on the location of the clicked control in the array are all done and working fine. I just can't seem to get the index of the control.
I need to know what entry (progress bar in this case) was clicked. In the function, I can even do things with a select progress bar using something like pb(x).value = some integer, but I'm trying to find out what 'X" is when the click event fires.
Here are some code snippets...
'Populate page 0 of tab control with progress bars
'TimerCount(int) = number of timer instances active in the database
For x = 0 To TimerCount
[code]....
EDIT: I figured out a work around using the 'name' property, but I would still like to know if what I asked about an index is possible.
One Tooltip For Control Array; Not One For Each Control?
Mar 27, 2012I have an application with as many as 625 Textboxes in a runtime generated control array.I add textboxes one at a time in a subroutine.The application ran with no problems until the parameters required more than 256 textboxes at which point it slowed drastically as textboxes were added. At circa 400 Textboxes it died with an out-of-memory condiiton.
The system has 8GB & a 64Bit version of Windows 7.It looks like the tooltips are eating up memory, causing excessive use of virtual memory from Hard Disk & finally causing out-of-memory.I am now running the application with a label which flashes when the mouse hovers. This uses the Handler for MouseHover.Is it possible to get a single Tooltip to function for all the Controls in an Array? I would prefer this to using the Event Handler.
Alternative To SQL CE?
Jul 15, 2010I'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 !
.net - Namespace With An Alternative Name?
Jan 27, 2011Using 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?

View 4 RepliesLooking For A Alternative To SendKeys?
Jun 8, 2010So I've been doing a lot of reading today and apparently SendKeys isn't very reliable anymore.Does anyone know of another alternative to it for what I need:
The application works by the form being positioned over a open window, notepad, word, excel etc and it then determines what it is over, notepad, word, excel etc and then reads the file, and does some processing using SendKeys at the moment.Though I do believe I could probably change the later at some point. The problem I'm having right now is when I try to send the Alt + Tab to change focus it's working roughly 12% of the time.If you are wondering I ran it 50 times and it worked 6 of those,thus the 12%.I'm thinking that is rather unacceptable.This is what I'm using which should work: SendKeys.SendWait("%{TAB}")

Sendkeys Or An Alternative?
Aug 30, 2010First off, using VB2010. I'm in the process of upgrading some applications from VB6 to 2010 and haveing a great time of it. The current application I'm working on is using Sendkeys of which I have changed over to the WSH.Sendkeys of which is pretty decent. Basically the program is copy and pasting the current open file, reading some data and saving it as a different file type. It also has to change xls files to csv and then saving it to the format as well as a smiliar thing with word. Thus the reason for the copy and paste as it's changing the extension to a dot date (for example, test.830).This is the flow of how it works for a text file (most basic)
1. changes focus to notepad
2. Select all Copy to ClipBoard
3. Open Programmers File Editor and a blank file
4. Paste in text
5. Save as code.date extension to the directory
Excel files obviously have a few extra steps.

View 4 RepliesWhat Is The Best .net Alternative To Dde For File Associations
Aug 13, 2009I have an MDI Windows Forms application (.net 2008) that allows the user to associate various file types with the application. I currently do this with a registry entry something like this, that causes the application to load and access the file name via the command line:[code...]
In the pre-.net version of the application, I used DDE (ddeexec in the registry). If an instance of the application was executing when a file was double-clicked in Windows Explorer, it would open the file without starting up a new instance of the application.
Now that DDE has been deprecated by Microsoft, what is the best way in .net for an executing MDI application to open an additional file when the file is double-clicked in Explorer, as opposed to starting a new instance of the application?
