immediate window

what is the utility of immediate window .i was getting opened in both the compile time as well as the run time

its to find the value of any int/char/string...

suppose you have a string STR that stores the value 'ABC' at runtime.

debug the project. after you have passed the line where this STR becomes equal to 'ABC', open up the immediate window and type '?STR' and press the enter key. you will see the value 'ABC' returned.

this is the same with any variable or any property of the objects.

try this..

when debugging, take the imm. window and enter '?Me.Name'. you can see the current form's name..

Then what's the diffeence between add-watch and Immediate window?

Xandip4-May-07 22:41

you can see the difference in the 'Watch window' itself..
during debugging, select any variable from the code and right click in the watch window and select the add watch option. you can see many options inside.
morover watch displays the value, type and context of the variable, but imm window shows only the value. also, imm window doesnt have the variety options that is provided by the watch window... got it?

The immediate window let's you query variables and execute individual statements while in design mode. You can read more here[^].

Learn how to write sql statements. Make sure you keep your code safe from injection attacks...

Sorting ListViewSubItems

I have a compare to sort the order of SubItems in a ListView and it works great, but... If the ListView shows Groups nothing is sorted. Here's the compare function from my class. How can I make it work when Groups are shown?

<br />
Public Function Compare(ByVal x As Object, ByVal y As Object) As Integer _<br />
    Implements IComparer.Compare<br />
<br />
        Dim ItemA As String<br />
        Dim ItemB As String<br />
<br />
        Try<br />
            ItemA = CType(x, Windows.Forms.ListViewItem).SubItems(_Column).Text<br />
        Catch<br />
            ItemA = ""<br />
        End Try<br />
<br />
        Try<br />
            ItemB = CType(y, Windows.Forms.ListViewItem).SubItems(_Column).Text<br />
        Catch<br />
            ItemB = ""<br />
        End Try<br />
<br />
        If _Ascending Then<br />
            Return [String].Compare(ItemA, ItemB)<br />
        Else<br />
            Return [String].Compare(ItemB, ItemA)<br />
        End If<br />
    End Function<br />

Hi
I am trying to create BMP file to print on Epson Receipt printers using OPOS. Epson printers only allow - BMP File which are Monochrome, 16 color (4 bit ) or 256 Color (8-bit) and should be uncompressed format.

I tried working 1bppIndexed Bmp. However the printer does not seem to except it. Currently the technique I am using is saving the image first as "GIF" ( 8 bit ) and then again saving it as bmp. However would like to know any techniquie for saving Uncompressed monochrome ( 1 bit ) bmp in Vb.net

Thanks

How to search through arrays

HurricaneDan4-May-07 7:17

4-May-07 7:17

I have two arrays. The first holds titles, the second holds text to see if the titles should be in a different case or bold. These names are then displayed in a Combo Box. Please bear with my simple example but it is about the only way to discribe what I want to do.

vNames = Array("Smith", "Hudson", "Jones")
VString = Array("H","I","h","i")

So I want to search the above vNames array for the vString, and if so I need it to be set to bold

This is what I was thinking:

For i = 0 To 2
For j = 0 To 1
If InStr(vNames(i), vString(j)) <> 0 Then
cmbName.FontBold = True
End If
Next j
Next i

But when I do this all three names are in bold, when my thinking is just the first two names should be bold.

Thanks in advance for any advice,

Dan

I'm assuming you're using VB6. This won't work because the FontBold property of the ComboBox is for all of the items in the ComboBox, not ones you pick. It's either all of the items are bolded, or none of them.

I am actually using vba for Word 2003, which I believe is much closer to VB6 than to anything else.

And you are right about it doing the whole list. One the name is picked it is added to a Word document text form field, what I believe I will need to do is this: set my txtName.Value, test for the string, then bold if need be.

Thanks for the reply.

The reason why they are all bold is because you are changing the combobox font to bold not the individual entry to bold.
