Re: Exposing a type safe collection for data binding

Duncan Edwards Jones14-Apr-03 22:13

It turns out I should have implemented IBindableList not IListSource.

Now the datagrid lists my control as a source in the DataBindings but it doesn't show any columns - I take it it doesn't know what the type safe collection type looks like? How do I add property descriptions to my existing class so the data bound grid can pick them up?

Problem on moving objects at design time

Hello

When I place a control at design time, normally, I can move the control by pressing UP DOWN LEFT RIGHT keys after selecting.

But nowadays I can't. When I press UP or DOWN or LEFT or RIGHT button; Vb.net moves the form, not the control.

Also when I right click one of the controls the commands wihch are Cut Copy Delete are disabled in the popup menu.

Sorry I can't use remotepicture linking. Because my site does not support it. You can see it http://www10.brinkster.com/eyazic/a/main.htm

Please help me it is very important, I can't design anymore

Thank you

You haven't said what control your trying to place. Is a standard toolbox control or a user control.

Also, is this a web or windows form and does this happen to all controls you now place?

It is possible to lock a controls position but the outline normally looks different to that shown in your screenshot but just check the controls properties and you should find a property named locked.

Thank you for your answer.

I already know the Lock property (in the popup menu)

But the problem is not connected with it. There is no problem on placing.
After placing when I try to move one of "ALL" objects it causes.

They are not locked.

Also I cannot use "CTRL+C" keys to copy or "Delete" keys to remove a control when this happens.

Length of a MenuItem in pixels

How can you define the length of a MenuItem in pixels in vb.net when you set... Ownerdrawnmenu to TRUE.

Problem: a MenuItem have a font (... Arial 8).

This MenuItem contains a Icon
This MenuItem contains a text (perhaps also a &-sign)
This MenuItem contains perhaps a Shortcut
This MenuItem refer to another Menu

Can this also in the menuheader?
(I think yes... I'm sure for the Icon... but I'have problemes with the length when I got the cursor on It...

Hiding columns in ListView

Hi,
I am new to vb.net and to this forum. Can anyone let me know how i can hide a listview column?

I am using the standard listview control available in the windows forms. I have set the view of the listview as Details. I need to hide the first column and for that i set the width property of the first column to zero. This makes the list view column invisible during the runtime. However if i place my cursor on the listview header and drag the same, the first column appears.

Is there anyway to hide the firstlistview column?

Thanks in Advance
Subha

Hello,

There is no other way to do it. You implemented is right thing. I just have a additional to tell you.

Assign ColumnResize value to none means one can not resize the column. Then while filling data in ListView calculate the length of the record which you are filling currently. Then assign the record lenght value to the column width. By doing this, you will able to see full length data in your ListView without facing problem.

Example for consideration:

Dim iLenght as Integer ' Lenght of the record
Dim iPrevMaxLength as Integer ' Length of previous record

iLength = 0
iPrevMaxLength = 0

While(rs.EOF != NULL)
'Todo part
.....
.....
.....
.....
iLength = len(rs.CurrentRecord)
if iLength > iPrevLength then
ListView.Column(index).width = iLength
iPrevMaxLength = iLength
end if
' Todo part
.....
.....
.....
.....
Wend

Let me know if this works or not.

Adding icons to menus in VB.NET

Retana Padilla has wrote a fine tool.
But...

(Excuse me, but my Englisch is not so good...)

I 'll try to use this code...
And make it better and better...
So I have set the EvMeasureItem.ItemHeight = 20
That is just enough to sign a rectangle round a icon (16*16) of 2 pixels width...

For instance I want tot use it in the header...
Then it goes wrong...
The second item in the header comes over the first item...
When I go over the first Item with the cursor
than you can't see the Icon in the second item in the header...

I think that the code have problems with:

The sub MeasureItems...
I don't understand very good how it's works.
Especially...
EvMeasureItem.ItemWidth = CInt(EvMeasureItem.Graphics.MeasureString (GetRealText(Mi), m_Font, 10000, sf).Width) + 10
(I have make it like this...
EvMeasureItem.ItemWidth = CInt(EvMeasureItem.Graphics.MeasureString (GetRealText(Mi), m_Font, 10000, sf).Width) + 30
It is better but not good enough...

And...
Also with the function GetRealText...
Can it be that sometimes the code don't got the real length in pixels?...

Another question is...
Is it also possible to manipulate the Item -----------------

I hope that someone can help me ...

Sort a collection

HI,

I've a collection which contains a couple of object I've created.
Is there a simple method to sort this collection or should I code a standard sort algorithm ?

Re: Sort a collection

if the Collection you are using is the one priovided by the .Net Framework(i.e. arrays, Arraylist etc.) you can just use:
Collection.Sort
But if the collection you are using is inherited, then you'll have to do the coding yourself.

Reference spreadsheet needs to be open

10-Apr-03 6:57

I have created a database query spreadsheet that pulls Customer ID's and corresponding Job ID's. There are a lot of calculations in this. I am using it as a reference for a separate Time Entry spreadsheet. If I use the Time Entry spreadsheet, I need to have the reference open. That might be too much for the user. I have 3 questions.

1. Is there a way to write a script that will open the reference and keep it invisible?

2. Should I just copy the cells from the reference into the timesheet and hide the tabs?

3. Will the CPU Usage be saved by choosing eother or will it stay the same?

My Brain hurts.

Thanks,

Don't use the add method. Try this:

Dim si As ListSubItem
Dim li As ListItem
Dim i, J As Integer

For i = 1 To 20
  Set li = ListView1.ListItems.Add(Text:="Item " & i)
  For J = 1 To 4
    Set si = li.ListSubItems(J).Text = "Subitem " & J
    si.ForeColor = vbRed

Calling an .exe inside VB.NET

9-Apr-03 5:26

Hi!
I have a program that only runs the way I want it to from cmd line. Such as:

> myprogram "c:\mydirectory\file.dll"

Now, I want to automate running this program against a lot of dll's so the argument in the cmd line is bound to change. And the other thing is, I need to parse the output of the program dumped to standard out. So essentially, what would be great is if i can call something like:

> myprogram "c:\mydirectory\file.dll" > output.txt

I have the following code so far
---------------------------------------------------
Dim p As New Process()
Dim p_info As New ProcessStartInfo()

p_info = p_info.RedirectStandardOutput = False
p_info.UseShellExecute = True
p_info.FileName = "myprogram.exe"
p_info.Arguments = "c:\mydirectory\file.dll"
p.Start(p_info)
---------------------------------------------------
I tried setting UseShellExecute to false and for some reason, myprogram doesn't launch properly.
I can't have UseShellExecute and RedirectStandardOutput both true. So how do I accomplish getting this standard out?

Thanks for the help!

Sort Array?

Hi,

I'm having a little problem sorting a 2 dimensional array, and I was wondering if someone could help. I want to sort the information in my array in decending numerical order. An example of my information is as follows: -

[50] [Bananas]
[10] [Lemons]
[30] [Oranges]
[100] [Apples]

I'd like it to sort the information from highest to lowest.

I'm using VB6, is this possible? Any help would be much appreciated.

Cheers

I'm afraid that there's no quick to way to do this, you'd have to do some coding. The best way, of course, if to implement a bubble sort through the first dimension, and change the second dimension accordingly
