To send an SMS from a computer you will need to subscribe to and pay for a service to send SMS texts.
The other option is to buy a cheap Android mobile phone and write something to connect to the device and send texts via the phone itself.
This second option would mean that you would need to look into programming with an Android device and write some sort of service to connect to the device via a wireless connection.

First of all this is my first thread, I'm new here so yeah, hello.
I would like to ask am i able to detect whether my webcam is being used by any other application.
The method I have in my mind is to put a timer and every time it ticked, It will check whether the webcam is running. Is this possible?
Please anyone? I have tried few but not able to.
Thank you.

Only if the device-driver supports it. Then it'd be a question whether there's an API for C#.

AFAIK, only by "trying" to use the webcam which would create problems of its own (like the webcam being in use by your app when the user tries to Skype with it)

I understand what you meant, but I didn't manage to do it. Can you help me with a little guide? I'm using Touchless SDK to connect to the webcam. I've tried my luck on their discussion room but it looks like a dead town there. No one ever reply any more.

..because most drivers will not support it.

Find an example here that tries to use the webcam. If it throws an exception, the webcam is in use.
Check it often enough, and the cam will always be in use (by you, making it unavailable for other apps).

Hello,
I am desperately trying to implement a VB .NET dll in a vb6 program without registration. I am completely new at this and no one in my company's IT department has needed anything like this so far, so there is no one to ask. I can get it to work on my PC without problems, but I can't get it to work on other PCs
So what I tried is this:
- Create a simple dll-class in VB .NET using Visual Studio 2010 (basically a hello world class)
- Make it com visible and register for interop services
- Compile (does compile for release or debug make any difference?)
- import tlb file in VB6
- compile VB6 project
Now I copied the dll and tbl files in the directory of the VB6 exe and tried creating a manifest.
I tried doing it by hand
using MMM
using UMMM
using mt32.exe
using Side by Side Manifest Maker
MMM: Creates an almost empty manifest. No reference to any dll found. Unsurprisingly this doesn't work on other PCs: "ActiveX component can't create object"
MT32.exe: Tryied creating a manifest out of the tlb and dll but I get "Automation error. Error in the dll"
UMMM: I was unsure how to configure the .ini file. What I have is this:
Identity C:\Program Files\Microsoft Visual Studio\VB98\TestDLL_UMMM\TestDLL.exe test "Test1.0"
File TestDLL.dll
-> "not a valid win32 application"
Side by Side Manifest Maker: Creates a manifest if I just add the tbl, but then I just get the "ActiveX component can't create object error". If I add the dll, it can't create a manifest because tlb.exe produces an error (translated from German): "a dependency couldn't be found. The assembly is being created by a runtime that is newer than the current runtime, and can't be loaded"
by hand: I can't actually find that version of the project. Suffice to say, I couldn't get it to work and I had no clue if I was even doing anything right 
I am now completely desperate and I have tried everything I could think of. I tried reading up on assemblies, manifests and how they work in VB6 and .NET, but nothing helped me in figuring out what I am doing wrong. Please help!

Don't; in the worst-case scenario it'd mean that one would have to register the tlb. The world will not end.

Unfortunately that doesn't help. I work for an international company in manufacturing. The VB6 software is installed on many PCs that serve as interfaces for the workers. They have just about zero permissions and cannot register dlls. Moreover, it is against company guidelines to allow them this kind of access
In short, it has to be registration free

Still doesn't mean you should be desparate; if it cannot be done because the customer does not want it, then that's the decision of the customer.
I'm out, sorry. Good luck.

Please I am doing a project that reads data from an excel sheet to a datagrid and the saves the data from the datagrid to an access database that will be created at runtime. The import to the datagrid has been done and even with that, the excel file needs to be opened literally before the datagrid can read from it. But as for the saving to the access database created at runtime, I have not been able to make any thing for it. Please help me. My project supervisor needs a working prototype by monday or by next week. Thank you all for your help.
You can PM me or email me for the source code.. Thank you once again

I'm afraid to have the wrong idea of how these forums work. When you find run up against a specific problem in your coding we will attempt to help YOU fix the issue. It is extremely unlikely someone is interested in doing your project work for you.
Debug you code to identify where and what the error is and post that information and we may be able to help.

Am sorry I didnt know how the forum works. I am truely sorry.. But the thing is I sent this not from my own machine so I couldnt retrieve the source code... And thanks for letting me know my ignorance levels.. I wouldnt do that next time

That's alright we all started out at some time, what you want to avoid is broad based questions, get into the detail and when you run into a problem do some research and if you still can't go forward then ask. I find 98% of my problems have already been solved by someone else.

The easiest way is having an empty database somewhere, and to make a new copy of that when you need to "create" one. File.Copy is easy, which would solve this problem. Bonuspoints if you tuck it in a resource-file and embed that in the executable.

How are you reading the Excel-file? Using an IConnection, with commands and stuff? You can do the same with the newly copied Access-database - put new records in one of the tables using an connection and some commands.

Thank you... I have managed to do most of the things that you guys outta here thought me. I have paused on the project for now. Will continue somewhere later since I have more learning and some exams to do.
Sorry I am replying this late. I truly am sorry for the late reply. I had no internet connection since that time... Thanks for your help buddies (serious and great programmers(my mentors)) outta here.
Better times... Greetings

Created a Crystal Report, Dragged Fields from the Fields List on Crystal Report.
Added a Report Viewer to Form

but when I add parameters it shows blank report
Here is the formula
IF (Length({?forMonth})>0) THEN
{tblFeePayment.ForMonth} = {?forMonth}
ELSE
TRUE
and below is the button Clicked event code
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Try
Dim cryRpt As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
Dim strReportName As String = "RptFeeReceipts.rpt"
Dim strPath As String = "D:\Projects\SchoolManagementSystem0821\School Management System\School Management System\Reports\ReportTest.rpt"
cryRpt.Load(strPath)
cryRpt.SetParameterValue("formonth", txtmonth.Text.Trim())
Dim frm As New FeeReceiptsPrint(cryRpt)
frm.Show()
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
And the FeeReceiptsPrint Code is here:
Public Class FeeReceiptsPrint
Private _cryRpt As CrystalDecisions.CrystalReports.Engine.ReportDocument
Sub New(ByVal cryRpt As CrystalDecisions.CrystalReports.Engine.ReportDocument)
_cryRpt = cryRpt
End Sub
Private Sub FeeReceiptsPrint_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
CrystalReportViewer1.ReportSource = _cryRpt
CrystalReportViewer1.Refresh()
End Sub
End Class
Pls Help,
Regards.

Hello, I am fairly new at programming, but I am learning. I am making a small application for my wife so she can record her babysitting scheduled through the week. Each day has three textboxes, the start time, the end time, and result. I need to know what to dim result as so I can insert the difference of the times entered into the textbox into the third textbox.
Public Class Form1
Dim startTime As String
Dim endTime As String
'Dim result As
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim dFrom As DateTime
Dim dTo As DateTime
Dim sDateFrom As String = startTime
Dim sDateTo As String = endTime
If DateTime.TryParse(sDateFrom, dFrom) AndAlso DateTime.TryParse(sDateTo, dTo) Then
Dim TS As TimeSpan = dTo - dFrom
Dim hour As Integer = TS.Hours
Dim mins As Integer = TS.Minutes
Dim timeDiff As String = ((hour.ToString("00") & ":") + mins.ToString("00"))
'result = timeDiff
End If
End Sub
Private Sub rbM1_CheckedChanged(sender As Object, e As EventArgs) Handles rbW1.CheckedChanged, rbTh1.CheckedChanged, rbT1.CheckedChanged, rbM1.CheckedChanged, rbF1.CheckedChanged
Dim rb As RadioButton = DirectCast(sender, RadioButton)
If rb.Checked = True Then
Select Case rb.Name
Case "rbM1"
startTime = m1start.Text
endTime = m1end.Text
'result = m1result.Text
Case "rbT1"
startTime = t1start.Text
endTime = t1end.Text
'result = t1result.Text
Case "rbW1"
startTime = w1start.Text
endTime = w1end.Text
'result = w1result.Text
End Select
End If
End Sub
End Class
<pre lang="vb">

I dimmed result as textbox and it works great

You must write the result to the Text property of that TextBox. When you do
startTime = w1start.Text
you read the text from the TextBox w1start into the variable startTime.
That is a oneway operation: it happens at that one moment when that line of code gets executed. No connection of the TextBox and the variable remains (if you want to do such a thing, look for "binding").
Hence when you want to update the value shown in the TextBox after changing the value of the variable, you need to do the operation the other way round:
w1result.Text = result
Do that after you assigned a value to result.
