Aligned Controls Swapping Place

November 27, 2017, 5:28 pm

I have a MDI Form with a StatusBar and PictureBox both Bottom Aligned.

The StatusBar is at the very bottom of the MDI Form and the PictureBox is sitting right above.

The Bottom Aligned PictureBox's height is sizeable by using the mouse to drag it's border making it bigger or smaller.

All works really well unless you start messing around and quickly drag the PictureBox border upwards. Doing this causes the StatusBar and PictureBox to switch places.

The PictureBox jumps to the bottom of the MDI Form and the StatusBar sitting above it.

Is there a way to 'Lock' an Aligned Control such as the StatusBar so that it will always be the lowest docked object?

Thanks.

Excel Automation Errors from VB6

November 27, 2017, 5:28 pm
$

I swear I think Windows 10 is just continuing to take backward steps.

As of some very recent Windows 10 update, I can no longer open XLSM or XLTM files from VB6.

I can't do ...

Code:
Set wbk = xls.workbooks.Add("SomeTemplate.xltm")
... nor ...

Code:
Set wbk = xls.workbooks.Open("SomeExcelFile.xlsm")
The first thing that happens is I get the following, which doesn't have the focus and gets behind my program's open forms, which is exceedingly annoying...

Name: e1.png Views: 44 Size: 4.6 KB

Once you find this message and click "Ok", then you get this (in the IDE, but same compiled)...

Name: e2.png Views: 33 Size: 4.6 KB

You click "Debug" and it shows you one of those lines like the above. If they're not macro files, all works fine. Also, just FYI, I'm running my Excel fairly wide-open:

Name: e3.jpg Views: 37 Size: 24.8 KB

Nothing I do seems to make any difference. I've added the file locations to the "Trusted Locations", and still no go. One thing that does work is to delete all the macros out of the Excel files, and then I can automate them. But this isn't a viable option.

Any Ideas,
Elroy

EDIT1: And just to add another piece, this is code that has literally worked fine for MANY years. We're not talking about new code. And it's been working on Windows 10 until quite recently.

EDIT2: Another piece is that I'm running Excel (Office Pro) 2010 on this machine. It'd take me a bit to set up a more recent version of Excel combined with Win10.

VS 2017 Hashing on VB.NET the same way Azure HashBytes Hashes

November 27, 2017, 5:45 pm
$

Hi

Im hashing a password on Azure using the HashBytes Function which is working great, but im having a problem producing the same hash on VB.NET because its using a string where HashBytes uses a Binary variable to hash against.

how can i duplicate whats happening with Hashbytes on VB.NET, the reason i need this is for compatibility and testing purposes.

ill post the code im using on both below

-Azure Code (SQL_transcript - stored procedure)
Code:
DECLARE @UserName VARCHAR(100),
                @Password VARCHAR(64),
                @PasswordSalt VARBINARY(64),
                @CustomerID INT,
                @HashedPassword VARBINARY(64)

BEGIN

--@Params is passed to the SP as a string

SET @UserName = (SELECT [Data] FROM dbo.Split(@Params , '|') WHERE ID = 1)
SET @Password = (SELECT [Data] FROM dbo.Split(@Params , '|') WHERE ID = 2)
SET @CustomerID = (SELECT [Data] FROM dbo.Split(@Params , '|') WHERE ID = 3)

--Create a 64bit random salt to add to the password
--not to interested in checking for duplicate salting in the DB since it would be extremely rare and does not cause an issue anyway
SET @PasswordSalt = CRYPT_GEN_RANDOM(64)

--Hash the salted password to get a 64bit hash
SET @HashedPassword = HASHBYTES('SHA2_512', CONVERT(VARBINARY(100), @Password) + @PasswordSalt)

--Prevent duplicate usernames
IF (NOT EXISTS(SELECT [ID] FROM [dbo].[tblUser] WHERE [UserName] = @Username))
        BEGIN
                INSERT INTO [dbo].[tblUser]
                        ([UserName], [PasswordHash], [PasswordSalt], [CustomerID])
                VALUES
                        (@UserName, @HashedPassword, @PasswordSalt, @CustomerID)
        END

ELSE
        BEGIN
                RETURN 2
        END

-VB.NET Code (this prehashes the password before its sent to the stored procedure)
Code:
Private Sub btnCreate_Click(sender As Object, e As EventArgs) Handles btnCreate.Click
        If Not CheckForm() Then Exit Sub 'this just checks all the fields are filled in properly

        'just a simple salting and hash on this side
        Dim PasswordHash As String = Hash512(txtPassword.Text, txtUserName.Text)
        Dim RetVal As Integer = 0

        RetVal = UpdateRecords_WithStoredProcedureB("SP_Name", "ConString", "SP_VarName", SP_Params)

        If RetVal = 0 Then
            MessageBox.Show("Account Created")
            Me.Close()
        Else
            MessageBox.Show("There was an error creating the account")
        End If

    End Sub

Public Function Hash512(password As String, salt As String) As String
        Dim convertedToBytes As Byte() = Encoding.UTF8.GetBytes(password & salt)
        Dim hashType As HashAlgorithm = New SHA512Managed()
        Dim hashBytes As Byte() = hashType.ComputeHash(convertedToBytes)
        Dim hashedResult As String = Convert.ToBase64String(hashBytes)
        Return hashedResult
    End Function
im hoping to find how to duplicate the procedure from the DB and use it in the VB.NET code.

Thanks.

[RESOLVED] Combobox - change text based on Item selection

November 28, 2017, 12:01 am

Hi,

I have a very strange requirement from users which I can' solve... I have a Textbox and Combobox beside It - whatever Item I select in Combobox, It' Text get's added into Textbox. So the output when selecting 2 Items from Combobox is "John Davies, Mike Burrough". This works fine.

Now what bothers user is design. They don't want to be able to edit in Textbox (that is solved) but also want to look this field same as Combobox only - without Textbox :).

So, the question is : Can I select an Item from binded/nonbinded Combobox and update Combobox.Text to achieve same result ??

This is the code that I use currently (Textbox + binded Combobox solution):

Code:
private void DrawText(TextBox txt, ComboBox cmb)
        {
           
            DataRowView drv = (DataRowView)cmb.Items[cmb.SelectedIndex];
     

            if (string.IsNullOrEmpty(txt.Text))
            {
                txt.Text = cmb.GetItemText(cmb.SelectedItem) + " " + drv["NAME"].ToString();
            }
            else
            {
                txt.Text = txt.Text + " , " + cmb.GetItemText(cmb.SelectedItem) + " " + drv["NAME"].ToString();
            }

        }

        private void Cmb_SelectionChangeCommitted(object sender, EventArgs e)
        {
            ComboBox cmb = (ComboBox)sender;
         
            switch (cmb.Name)
            {
                case "Combobox1":
                    DrawText(Textbox1, cmb);
                    break;

                //... and so on
            }

        }
I know It's a weird question, but maybe It can be done, so thanks for help in advance !

Hi

I am using VS 2015 and Office 2010

I have a code in VB.NET that exporting a listview to excel.
The export complete just fine and the excel sheet look OK.

The problem is that when I go to the end of a column
I can't use the SUM() function of the excel.
No matter what I do inside sheet Sum returns always zero.

If I edit one or more of the cells in the column I want to summarize
then the Sum() working fine. just pressing F2 and Enter in the cells.

What I am doing wrong?

Here the code I am using.

Code:
Dim ExcelApp As Object
Dim ExcelBook As Object
Dim ExcelSheet As Object
Dim i As Integer
Dim j As Integer
Dim m As Integer
'create object of excel
ExcelApp = CreateObject("Excel.Application")
ExcelBook = ExcelApp.WorkBooks.Add
ExcelSheet = ExcelBook.WorkSheets(1)
ExcelSheet.visible = True

With ExcelSheet
    'fill excel with values
    For m = 0 To LST.Columns.Count - 2
        .cells(1, m + 1) = LST.Columns(m).Text
    Next
    For i = 1 To LST.Items.Count - 2
        If IsNumeric(LST.Items(i - 1).Text) Then
            .cells(i + 1, 1) = String.Format("{0:n2}", Decimal.Parse(LST.Items(i - 1).Text))
            .cells(i + 1, 1).NumberFormat = "0.00"
        Else
            .cells(i + 1, 1) = LST.Items(i - 1).Text
        End If
        For j = 1 To LST.Columns.Count - 2
            If IsNumeric(LST.Items(i - 1).SubItems(j).Text) Then
                ' Check for the Code field, do not to print decimals
                If j = 1 Then
                    .cells(i + 1, j + 1) = LST.Items(i - 1).SubItems(j).Text
                Else
                    .cells(i + 1, j + 1) = String.Format("{0:n2}", Decimal.Parse(LST.Items(i - 1).SubItems(j).Text))

Which Windows DLL actually has RtlCopyMemory?

November 28, 2017, 5:33 am
$

According to MSDN, RtlCopyMemory is faster than RtlMoveMemory (though RtlMoveMemory is often aliased as CopyMemory in VB6 declarations). So I scrolled down the MSDN page and found where it says what DLL to find it in. And there I see it say "NtDll.dll (user mode)", so I know what DLL it should be in, and I use this declare statement:
Code:
Private Declare Sub RtlCopyMemory Lib "ntdll.dll" (ByRef Destination As Long, ByRef Source As Long, ByVal Length As Long)
Unfortunately this doesn't work when I actually call the DLL function in my test program:
Code:
Private Sub Form_Load()
    Dim a As Long
    Dim b As Long
    a = 5
    RtlCopyMemory b, a, 1
    Print b
End Sub
I end up getting an error that says "Can't find DLL entry point RtlCopyMemory in ntdll.dll". So which DLL is it in? There's tons of DLL files in the Windows system folder. And it's not like it's an undocumented function either. It's documented on MSDN, so if MS moves its location, then there's going to be a lot of programs out there that use it that will now break.

Here's the MSDN page for it https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx

Error "Object reference not set to an instance of an object."

Hi all,

I'm using the following code to read data from a DataGridView row. It works fine.

Code:
Private Sub dgvGamesList_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvGamesList.CellClick

I = dgvGamesList.CurrentRow.Index

'...... READ DATA FROM THIS ROW
'...........

End Sub
However, for this code to work you need to click each row with your mouse. It won't work if you select the rows using the arrow keys. So, I tested the following code, but I got the "Object reference not set to an instance of an object." error. The error is pointed to the line "I = dgvGamesList.CurrentRow.Index"

Code:
Private Sub dgvGamesList_RowEnter(sender As Object, e As DataGridViewCellEventArgs) Handles dgvGamesList.RowEnter

I = dgvGamesList.CurrentRow.Index

'...... READ DATA FROM THIS ROW
'...........

End Sub
How can I run my script using the "CurrentRow.Index", so that it works whenever a row is highlighted? Any help is greatly appreciated.

Thanks,

"conditional" dim type

Hello All.

I have a procedure I call from 2 different areas in my app/

The procedure does the same thing for both situations, but in one case must have one of its internal variables declared as type A and in the other case the same variable must be declared as type B.

So, the following obviously does not work, I am aware that you can not do a Dim inside and if statement. This is where I need a solution. A non-declared variable would work, but i like it better for 'clean' & ease programming and intellisense.

Code:
Public Sub FillHistoryGrid(ByRef TempmyVar)
      If condition = true Then
          Dim myVar As New List(Of Type5)
      Else
          Dim myVar As New List(Of Type6)
      End If

      myVar = TempmyVar

      ...
end sub
Any ideas?
