Hello !
I'm using Entity framework 6 with Sql server 2008r2.
But I have noticed that even a small query ( with only 2-3 records ) need about 25 seconds to execute.
This happens everytime when I execute a query for the first time.The second time is more fast. But if I open another form and execute another query , there's again a delay.
what can I do ?
Thank you !

This was a problem with EF 6.0 that has been fixed in the latest update, I believe it is 6.0.2 that fixes it.
Open the Package Manager console in your project and type
Update-Package EntityFramework

Hello !
I have update it , but it's the same situation.
|

|

In that case I have idea what it is.

Hello !
I thought to use Pre-Generated views.
I have installed "Interactive Pre-Generated Views for Entity Framework 6 "
- On Console Manager : install-package EFInteractiveViews
- On my main form I have this :
Imports InteractivePreGeneratedViews
Private Sub IntViews()
Using ctx = New MyEntities()
InteractiveViews.SetViewCacheFactory(ctx,NewFileViewCacheFactory("C:\Myprog\MyViews.xml"))
End Using
End Sub
Now I get 2 errors :
Error 104 :
Error 105 : Type
What can I do ?
Thank you !

I have no idea. I've never used that.
I'm still on EF5.

Hello everyone,
I want to create a text file when a program loads for the first time and refer it every time when we load the form or activate the form.
Open "C:\" & "filename.txt" For Output As #1
register = CStr(Date)
Print #1, register
Close #1
This sample code is working on Win XP but its not creating txt file in Win 7. Please let me know how to make them work in 7 or 8 as well. Thanks in advance.

reason for it not working on Win7 is UAC[^].
it is suggested that you then look at writing files into the app data folder of the user.
The first answer from this link[^] gives you a good example of how to do it

Why would you START a development in a tool that has been dead for a DECADE. Get the Express version of VB.Net.

The code below works like I want it to so far, by selecting specific cells in one worksheet and pasting in specific columns on another. When I change the data is D10, D12 and D14, how do I get it to paste on the other worksheet in the next available cell for that column?
Sub Button1_Click()
lMaxRows = Sheets("Sheet4").Cells(Rows.Count, 4).End(xlUp).Row
Sheets("Sheet4").Cells(lMaxRows, 4) = Sheets("Sheet1").Range("D12")
Dim LR As Long
Sheets("Sheet4").Select
'your paste to sheet name
'Last Row in "Sheet4" - change column as you need
LR = Sheets("Sheet4").Range("D" & Rows.Count).End(xlUp).Row
Range("D" & LR).Select
'change A as you need - it selects the last row
'Paste
lMaxRows = Sheets("Sheet4").Cells(Rows.Count, 5).End(xlUp).Row
Sheets("Sheet4").Cells(lMaxRows, 5) = Sheets("Sheet1").Range("D14")
lMaxRows = Sheets("Sheet4").Cells(Rows.Count, 5).End(xlUp).Row
Sheets("Sheet4").Cells(lMaxRows, 6) = Sheets("Sheet1").Range("D10")

What libraries are you using? Interop with Excel, or a third-party?
As it reads, the first two lines should do the trick; you're fetching the last cell, and writing the contents of Sheet1$D12.

Pasting is a lousy way of aggregating choices. Launch VB, read that file, and write a decent UI for it.

I thought it would work too, but when I change those cells it just copies over the previously pasted data.
I am very new to this, so I dont understand everything.

Copying/pasting is not behaviour that applications should override; the clipboard is an OS-function. Most likely it's Windows that's biting you 
Ensure that it does find the "next free row", or take the time to write a UI. A CheckedListBox sounds convenient; you show your options, the user presses "spacebar" to select an item, or cursor-down to go to the next item. Wouldn't that be a friendlier way to get a selection?

Again, I am new at this. None of what you just said makes any sense to me. Do you know how to help me figure out how to make my code work?

All of us started that way.

Copying/pasting is something that's baked into Windows; and it's hard for applications to change it's behaviour, because it's deemed an important function.
Can you give me a brief idea of what you're trying to achieve? It looks like you want to have the user make a list of things.

I'm not on a machine with Excel atm, but I'll be running the code later. As the second line of code, insert the line below;
Sheets("Sheet1").Cells(1, 1) = lMaxRowsThat should tell you what is considered to be the "next free cell".

Here is what I am trying to achieve.
I have one workbook, with two different sheets (Sheet1 and Sheet4). I am trying to copy the following cells on Sheet1 to specific cells/columns in Sheet4 with the click of a button.
Sheet1 D10 to Sheet4 column B in the next available cell
Sheet1 D12 to Sheet4 column D in the next available cell
Sheet1 D14 to Sheet4 column E in the next available cell
Sheet1 E22 to Sheet4 column C in the next available cell
Right now I can get it to work in terms of getting the cells to copy and paste properly to sheet4, but when I click the button again, it just replaces the information in those cells. Every time I click the button, I will need it to fill in the next available cell for the columns listed above.
Your help is appreciated.

Here is what I would have done (20 years ago).
Turn macro recorder on
Navigate from the source cell to the destination location using the keyboard. This will give you an idea how the macro coding works, you will need to modify it to look for the next vacant row.
Now in code get the contents of the D## cells into variables.
Navigate to the next empty row. Set the values from the variables into the required cells.
Inform the user the job is done.

Looks like you're building a macro in Excel itself; the code didn't work from a new VB.NET application. The "rows" should be prefixed with the sheet that they're coming from, and xlUp wasn't recognized.
There's also no concept of a "next available cell".
