Well, I found the source for the utility your using. It's at http://www.codeguru.com/system/DiskId32.shtml. The only problem is, your going to have to recode it to be directly usable in VB, possibly as a DLL.

The easier way to do it is to pipe the output from the program to a text file with something like: MyApp = Shell("Diskid32.exe > log.txt", 0) You might have to use another method to get this to launch properly. But, in any case, what your going to have to do is open the log.txt file and parse it up to pull the information out of it.

It's better than writing a custom DLL to do the job...

Does anyone have or know where I can get hold of a ListView control which can be used in VB6 with the capability of multi-line ColHeading's?

If not I will see about creating my own, in C++ for use in VB6.

previously, when generating reports, I entered a range of dates by means 2 textboxes. However, for the purposes of validation, i found this an inadequate way (eg it allows entry of days > 31 etc). instead i have started to use an MaskEdBox, i have set the DataFormat to Date, how do i set the format to ##/##/####? does it have similiar properties to that of the textbox? (ie MaskEdBox.Text etc)any help would be greatly appreciated, i am a newbie to this control!Thank you!

MaskEdBox1.Mask = "##/##/####"

You will need to check the values to make sure that the user entered the correct values, I would suggest you write a function:

Private Sub MaskEdBox1_KeyPress(KeyAscii As Integer)
'Do your stuff here...
End Sub

Why dont' you try a DTPicker control - resembles a Combo, but when you hit the drop-down, it shows a Month in a calendar control. Still possible to directly enter a date, but won't let you enter an invalid one.

To use, right click your toolbox and select components. Scroll down the resulting list, and select "Microsoft Windows Common Controls 2 6.0 SP4", or browse to MSCOMCTL2.ocx. This will add the control to your toolbox, and can be used in the normal way. Help for the control is in MSDN under VBReference->Controls Reference->ActiveX COntrols

syntax error in update statement

Dim updateSQL As String
updateSQL = "Update Product Set " & _
" Description = '" & txtDesc.text & "', " & _
Confused | :confused:

" Where Code = '" & txtCode.Text & "'"
Set RS = Conn.Execute(updateSQL)

This statement executes fine when i test it in access but here, it returns the above error. I have checked that all the fields are the same as that in the database and the textboxes match aswell. Neither txtcode or txtDesc are bound to any component. What could the problem be? if you need any more information, please let me know, any help would be greatly appreciated!!

You don't need the comma after the txtDesc.text. So the correct SQL command should work with:

updateSQL = "UPDATE Product SET Description = '" & txtDesc.text & "'" & _<br />
            "WHERE Code = '" & txtCode.text & "'"<br />
<br />
Set RS = Conn.Execute(updateSQL)

Row headings in MSHFlexGrid (VB6)

I have an app written in VB6 which uses the MSHFlexGrid. I would like to add heading to the columns which have two lines. Is it possible to use a CR in the heading text or am I forced to use two rows?

If as I suspect I have to use two rows, how do I hide the row lines in the heading rows?

Hi, I want to make such a software in which i want to connect my SQL database situated on a remote server to the software residing in my PC. So is there any other apporoach other then creating the DSN and using it with ADO?

Please tell me to be a professional software developer should i develope command over VB of VC++

Regards

Think that you may be misunderstanding things here a little. If you specify a DSN in an ADO conneciton string, the conneciton will actually go through the ODBC driver / layer. However, if you specify a connection string of the format:

strConnString = "Provider = SQLOLEDB;Database=<DBNAME>;<br />
Datasource=<SERVERNAME>"

Then the OLEDB provider for SQLServer will be used to connect to the machine specified by <servername> and the database specified by <dbname>. You'll also have ot provide a UID and PWD though.

Hi all,

Friend asked me the following question, and since I do not know VB at all, i'll try it here.
So, in a Excel macro, he wants to set the active printer as "\\NTS198\\PFK" which is our color printer. But the port used to install the printer differs from user to user, that is, name of the printer in Excel is sometimes "\\NTS198\\PFK auf Ne02" or "\\NTS198\\PFK auf Ne01". and using Application.ActivePrinter() will throw an error if the name of the printer is not correct. So my question is, how do I find the port on which the "\\NTS198\\PFK" printer is on, so that i can use Application.ActivePrinter() without error ?

Foreign Key Constraint Message

Hi...Sorry to be a pest. Perhaps related to my earlier post, but I'm getting the following message when I preview the dataset in the IDE: ForeignKeyConstraint 'EmployeeComments' requires the child key values (115) to exist in the parent table.

This doesn't make sense. The relationship seems easy enough. The primary key and foreign keys are the same as far as Interger (8), nulls not allowed. Any ideas.

Thanks in advance,

Mike

Simple. You have two tables (Table1 and Table2). Table2 has records that relate to records in Table1. The only thing holding the relationship is the fact that the two tables share a common field:

Table1: Table2:
recID ID# of record recID ID# of record in table 1
Name Some name Info1 Some information related to table1
Address Some address Info2 Some information related to table1

Both tables share a recID field. But, Table2 can have multiple records with the the same recID from Table1, this is a 1-to-many relationship. One record in Table1 is related to Many records in Table2.

The problem your running into is there is a recID in Table2 that doesn't exist in Table1. It's a record that doesn't have a relationship to any record in Table1.

You can probably code a SELECT statement to find the 'orphaned' records in Table2 for you, but I don't know exactly how to do it.

Hi...I've designed a form (winform) using VB.net standard. I used the data form wizard to construct it. It has a parent table record and 2 child table datagrids connected via oledb. I'll get into the construction when all of a sudden I get this message "DataBinding could not find a row in the list that is suitable for all bindings." What the hell is this? I can't find it anywhere in the knowledgebase or newsgroups. It is driving me crazy. The form code (.vb) is still there but the form (designer) is all screwed up. This has happended several times. Am I the only one who has experienced this. Microsoft....are you there? Mad | :mad:

Thanks in advance,

I only need to list items with user interfaces (windows) not services.

Any ideas apreciated.

Dim processes As Process() = Process.GetProcesses

Dim ThisProcess As Process
For Each ThisProcess In processes
'-- Ignore the current process
If ThisProcess.Id <> current.Id Then
'-- Only list processes that have a Main Window Title
If ThisProcess.MainWindowTitle <> "" Then
ListBox1.Items.Add(ThisProcess.ProcessName)
End If
End If
