I'm trying to create a control array in VB2005. As I've said in other questions, I've been working in VB5 for a good while but I'm new to VB2005. I know how to set the array up in VB5 but it doesn't work in VB2005. I tried some code that someone told me about, but it's not working. I have several books on programming VB2005 but
Here's my code as it stands now:
Public
Class frmMain
Public lblFasting(30)

In VB6, if I copy and paste a combobox on the form, VB6 automatically asks if I want to create a control array. VB2005 does not do this when I copy and pasted on the form. How can I create control array for comboboxes on the form similar to VB6 method?

View 1 RepliesI've been working with a sig capture application sample on a windows mobile device, The data is sent via IP to a host as a byte array and is then drawn onto the screen of the host as it appeared on the client. I was able to get this into the form of a bitmap object so I could print it or save to a jpg file. That all works well. The problem now is that I need to store this data in a database and then be able to recall it at a later time and recreate the signature image.
The byte array data is much smaller than the actual image so I would like to store it in that form. My issue is that when I convert this byte array into a string and back again my program can no longer re-create the image. Once I saw the problem I created the code below as a test and added the msgboxes to get an idea what was happened to my data.

View 4 RepliesIt was so simple in VB6 but I don't know how to approach it in VB2010. I've looked the internet but each site seems to have a different solution and masses of code for something that could be done in a few lines in VB6.Here is the code I want to use. How do I go about creating a control array of 100 picture boxes pic(1) up to pic(100)?
Code:
For y = 0 To 9
For x = 1 To 10
tempObject = (Mid(StrRow(y), x, 1))

View 8 RepliesI'm trying to upgrade a VB 6 project which uses a component called MSGrid, or grid32.ocx; the conversion seems to have a problem finding a more modern replacement for it. When I try to open a form that uses the grid control, I get
One or more errors encountered while loading the designer The designer cannot process the code at line 289: CfGrid.OcxState = CType(resources.GetObject("CfGrid.OcxState"), System.Windows.Forms.AxHost.State) The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.
But I can't remove the changes since I can't get into the form designer on account of the error. I don't need a data-bound control, just a simple grid. How do I remove the offending object and replace it with a more acceptable version?

I need my app. to Create an Control Array at runtime that will consist of up to 50 Data Bound Labels. The app. will first be checking the 1st database field (Ing1) to see if there is data, if so then only create the 1st Data Bound Label (lblIng1) and then check the next field and so on.
The problem is that VB 2008 dos not seem to support Control Arrays. There must be another way to work around this.

View 9 RepliesThis was an experiment to see if I could create a fake array using generics instead of using an array. I decided to try it, because I may use it if I find any advantages to using it over an array. it works, I am just asking for a second or third opinion, have I screwed anything up, or is there an easier way to accomplish this? If I use it, it will be for a 2D game I am creating, and is used to draw the 2D screen graphics, placing an image based on what image identifier is located at what coordinates. The value stored in the fake array is an integer that disignates the graphic to draw and whether it is passible or not, i.e. 0 = a floor image, 501 = a wall image that is impassible (any image number > 500 is impassable) The Class definition:

I 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.
For l = 1 To 3000
Led.Load(ledCounter)
ColLed.Add(Led(ledCounter))

The 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)

I have an array of picture boxes as so:
Dim pieces(500) As PictureBox

And is 'Control Array' the correct term for this? or something else?
I 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

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.
I 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.
I want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like
array2(0)... contains a collection of array1 data
array2(1)... contains a collection of different array1 data
.. and so on
i think i need to make new instances of array1 each loop, but not sure.I dont mind if it uses arrays, or arraylists, or lists, or structure of arrayslists?
