Don't do this. DOn't rely on the states of controls to control the state of your application. Maintain the state in your own structures seperate from what controls are telling you. This way, you have better control over what's going on in your application without having to deal with the side-effects of control values. For example, checking Control.Visible will change depending on if the user can actually see the control. It may change if the user drags another window over the top of the control in question.

Hi, I want to implement a funciton on a button, like:
click 1, text="aaa";
click 2, text="bbb";
click 3, text="aaa" = click 1;
click 4, text="bbb" = click 2;
that is, the text would flip-flop with the clicking action.
Now I thought a method that I can do this with a variable to represent the status of the button.
Is there other way to do that flip-flop button function?

Thanks, could you give me a simple example on how to use the "OnMouseDownClickCount", and "MouseButtonDownHandler"?
I added a button in a form, just want to test these 2 handler, but don't know how can I connect these 2 event handler with a control.
Thanks
|
|

|

Yes, you are right.
Declare the variable at the "Form" level and you will be able to manipulate the text of the button.
You could do this with a boolean.
Dim butClicked as boolean = False
Inside your button click event.
If (butClicked) then
set text to aaa
else
set text to bbb
butClicked = Not butClicked

Hi developers .I have some problem in my project which is on employee timein and timeout.when an employee login in the morning my timein button should accept the timein and add it to the database(ms access).when an employee wants to logout in the evening the timein and timeout form should validate the timein field in the database if timein field contains the login time then form button should active as timeout ,but it is not validating in my project so kindly can anyone help me.so here is my code..:
Dim CN As New OleDbConnection(cnString)
CN.Open()
once if the employee login by its e-id and password it shows the e-name,inthe another textbox.so to select the ename i have coded below.
com2 = New OleDbCommand("SELECT ename from Images WHERE eid ='" & txtemid.Text & "' ", CN)
dr = com2.ExecuteReader
While dr.Read
txtename.Text = dr(0)
'Please below given line is to extarct the only current time except date
txttime.Text = Now.ToShortTimeString
"Now here it is validating for timeout "
com3 = New OleDbCommand("Select * from logtime where eid='" & txtemid.Text & "' and timein<>null and timeout=null and present=null ", CN)
dr1 = com3.ExecuteReader
If dr1.Read Then
Button1.Text = "Time Out"
txttimeout.Text = Now.ToShortTimeString
Exit Sub
Else
End If

Hi guys,
I need to find text with a specific font color and change its color to another one.
This is more or less what I got:
With ActiveDocument.Content.Find
.ClearFormatting
.Text = ""
.Font.Color = RGB(102,102,153)
With .Replacement
.ClearFormatting
.Text = ""
.Font.Color = RGB(80,176,0)
End With
.Execute Replace:=wdReplaceAll
End With
Problem is: this worked in Word 2007, but in Word 2010, the Font.Color property seems to be dropped. I've tried with Font.ColorIndex and Font.ColorIndexBi, but it doesn't do anything. I can only select a few predefined colors (and clearly it doesn't contain the colors I need  )
I prefer to avoid looping through every character if possible. Since we're talking about documents that can contain up to 100k words (and more), it wouldn't be really performant, at least not performant enough to use it on let's say 35 docs in batch .
Anybody an idea about how to bypass that palette restriction?
Thanks you guys

The easiest way of deiling with this, is to open a Word 2010 document, start recording a macro. You select the text and change the front color. Stop the macro and look at the code, it should be there
Edit:
It wont work for shapes though 
|
|
|
|
|
I'm going to try that Shapes are not an issue (in this case)
And why on earth didn't I think of that 
|
|

Hi,
I recorded it and came up with the following code
Selection.Find.ClearFormatting
Selection.Find.Font.color = RGB(102, 102, 153)
Selection.Find.Replacement.ClearFormatting
Selection.Find.Replacement.Font.color = RGB(0, 176, 80)
With Selection.Find
.Text = ""
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindContinue
.Format = True
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
End With
Selection.Find.Execute Replace:=wdReplaceAll
Cheers!

I have installed the Crystal report for vs 2010. I want to generate the crystal report for my project. I have written the following code on button click event.
Private Sub btnPreview_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPreview.Click
Dim sqlQRY As String = "SELECT * FROM Customers"
Dim cmdExec As SqlCeCommand = New SqlCeCommand(sqlQRY, conn)
Dim da As SqlCeDataAdapter = New SqlCeDataAdapter(sqlQRY, conn)
Dim ds As DataSet = New DataSet
da.Fill(ds, "Customers")
Dim Report As frmReports = New frmReports
Dim mReport As rptCustomers = New rptCustomers
mReport.SetDataSource(ds)
Report.CrystalReportViewer1.ReportSource = mReport
Report.ShowDialog()
End Sub
But when i run the program I got the following error. What to do?
"Could not load file or assembly 'file:///C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified."

Hi,
I'm relative new in vb.net programming, so I have some questions about printer settings, printer properties.
How could I share a local printer? Also I would like to access another PC and share a printer installed on that computer. How could I do that?
I used the following vbscript code, but I can't convert it to vb.net:
strComputer = "w20hy050"
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colInstalledPrinters = objWMIService.ExecQuery _
("Select * from Win32_Printer Where Name = 'Customer'")
For Each objPrinter in colInstalledPrinters
objPrinter.Shared = TRUE
objPrinter.ShareName = "Customer"
objPrinter.Put_
Next
Thanks for your help.

There's a Proces class that you can use to launch your vb-script.

You'd probably need local admin-rights on that computer.

That script uses WMI. WMI can also be used in .Net programs.

C# and VB.NET are both translated to IL. If converting it breaks it, then don't convert it. You can reference the code from any .NET language, as long as you have a compiled assembly.

I am getting this Error:
Quote: Index was out of range. Must be non-negative and less than the size of the collection.
I have two winforms, and i am trying to pass data between them
Form1 has Gridview which binds to a Store procedure that selects 8 parameters from a "Guardian Table".
form2 has 8 textboxes that I want the data from Form 1 to be displayed
what I want to do is by clicking "LookUp" Button (On FORM2) to get to FORM1 and get the selected row data (when the user selects one row) and display it on form 2
Now here is my code for both forms:
Public Sub getChangesFromForm2(ByVal text1 As String, ByVal text2 As String, ByVal text3 As String, ByVal text4 As String, ByVal text5 As String, ByVal text6 As String, ByVal text7 As String, ByVal text8 As String)
DataGridView1.SelectedRows(0).Cells(0).Value = text1
DataGridView1.SelectedRows(0).Cells(1).Value = text2
DataGridView1.SelectedRows(0).Cells(2).Value = text3
DataGridView1.SelectedRows(0).Cells(3).Value = text4
DataGridView1.SelectedRows(0).Cells(4).Value = text5
DataGridView1.SelectedRows(0).Cells(5).Value = text6
DataGridView1.SelectedRows(0).Cells(6).Value = text7
DataGridView1.SelectedRows(0).Cells(7).Value = text8
End Sub
FORM 2:
Private Sub LookUpBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LookUpBtn.Click
GuardianBasicList.getChangesFromForm2(GuardianIDTxt.Text, GuardianPhoneTxt.Text, GuardianFNameTxt.Text, GuardianMNameTxt.Text, GuardianLNameTxt.Text, GuardianEmergContFNameTxt.Text, GuardianEmergContLNameTxt.Text, GuardianEmergContPhoneTxt.Text)
GuardianBasicList.Show()
End Sub
What am I doing wrong? is there another way of achieving the same result??
ANY HELP given is highly appreciated.
Thank you

VB.Net is not my strong suit, But You should be passing the info as a class in your form2 constructor. Then just assign the data to the text boxes.
Hope this helps
