Re: VB CODE TO RECEIVE SMS THROUGH GSM MODEM - Visual Basic Discussion Boards

You have already asked once - please don't repost

I'm an optoholic - my glass is always half full of vodka.
=========================================================

on my previous post, i'm asking help for making .gif using different images in one picturebox. And to my latest post, i'm asking how can i save .gif(in picturebox) as .gif to mydocuments/computer. It's totally different although its related to ".gif"

You could use the following code to save a GIF image in a Picture Box(PictureBox1)

PictureBox1.Image.Save(SpecialDirectories.MyDocuments + "\MyGif.gif", ImageFormat.Gif)

Note: Import the following

System.Drawing.Imaging
Microsoft.VisualBasic.FileIO

Where in the above code is the part that saves the image? Please do not just dump a lot of code and expect us to work out what it is supposed to do; provide proper detailed explanation.

hello everyone

I need your help to achieve my MapWinGIS project Visual Basic.NET,
I wonder how to write a procedure that allows viewing the positions on the map with the symbology of my choice and displayed according to the selection in the legend group using the CheckedChanged event categories.

thank you

hi, will somebody give me a code in vb which will be able to receive sms using a usb gsm modem?
please help. thanks.

No. That's not how it works around here.

We'll help you with problems with YOUR code, but not write it for you.

You're not writing our code for us while we're writing your code for you, so...

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 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 :

VB

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 :

VB

Error 104 : 'InteractiveViews' is not declared. It may be inaccessible due to its protection level.
 Error 105 : Type 'FileViewCacheFactory' is not defined.

What can I do ?
Thank you !

I have no idea. I've never used that.

I'm still on EF5.

Hello !
I've read about it in this link :
http://blog.3d-logic.com/2013/12/14/using-pre-generated-views-without-having-to-pre-generate-views-ef6/[^]

If you have some time , can you read and give me an idea what I did wrong ? ( Please ! )

Anyway thank you !

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.

SQL

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

how can i develop 8-puzzle game in order to work automatically rather than manually? by using vb6.

mpk

You can start by reading this post![^]

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

how can i develop 8-puzzle game in order to work automatically rather than manually?

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.

Bastard Programmer from Hell Suspicious | :suss:

If you can't read my code, try converting it here[^]

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.
