How to call IP Camera API in VB6

Private Sub Command1_Click()
    SaveCameraImage "http://192.168.1.2/ISAPI/streaming/channels/01/picture", "username", "password", "C:\MyImages\camera_image_" & Format(Now, "yyyyMMdd_HHmmss") & ".jpg"
End Sub

Private Sub SaveCameraImage(ByVal sURL As String, ByVal sUsername As String, ByVal sPassword As String, ByVal sSavePath As String)
    Dim oHttp As WinHttp.WinHttpRequest
    Dim oStream As ADODB.Stream
    Dim bSuccess As Boolean

    On Error GoTo ErrorHandler

    Set oHttp = New WinHttp.WinHttpRequest

    oHttp.Open "GET", sURL, False ' Synchronous request
    oHttp.SetCredentials sUsername, sPassword, HTTPREQUEST_SETCREDENTIALS_FOR_SERVER
    oHttp.Send

    If oHttp.Status = 200 Then
        Set oStream = New ADODB.Stream
        oStream.Type = adTypeBinary
        oStream.Open
        oStream.Write oHttp.ResponseBody
        oStream.SaveToFile sSavePath, adSaveCreateOverWrite
        oStream.Close
        Set oStream = Nothing
        bSuccess = True
        MsgBox "Image saved successfully!", vbInformation
    Else
        MsgBox "Error: " & oHttp.Status & " - " & oHttp.StatusText, vbCritical
        bSuccess = False
    End If

    Set oHttp = Nothing
    Exit Sub

ErrorHandler:
    MsgBox "An error occurred: " & Err.Description, vbCritical
    bSuccess = False
    If Not oHttp Is Nothing Then Set oHttp = Nothing
    If Not oStream Is Nothing Then oStream.Close: Set oStream = Nothing
End Sub

Hello! It's great to hear about your interest in accessing an IP camera API in VB6. To achieve your goal of saving an image to a folder upon clicking a button, you can follow these steps:

1. Making HTTP Requests: In VB6, you can make HTTP requests using the `MSXML2.XMLHTTP` object. Here's an example of how you can make a request to the camera's API and retrieve the image:

Dim objHTTP As Object
Set objHTTP = CreateObject("MSXML2.XMLHTTP")
Dim url As String
Dim username As String
Dim password As String

url = "http://username:[email protected]/ISAPI/streaming/channels/01/picture"
username = "your_username"
password = "your_password"

objHTTP.Open "GET", url, False, username, password
objHTTP.send

If objHTTP.Status = 200 Then
    Dim responseBody As Variant
    responseBody = objHTTP.responseBody
    
    ' Save the image to a file
    Dim outputStream As Object
    Set outputStream = CreateObject("ADODB.Stream")
    outputStream.Type = 1 ' Binary
    outputStream.Open
    outputStream.Write responseBody
    outputStream.SaveToFile "C:\Path\To\Your\Folder\image.jpg", 2 ' 2: Overwrite if exists
    outputStream.Close
End If

Set objHTTP = Nothing

2. Button Click Event: You can trigger this code when a button is clicked in your VB6 form. Simply add a button control and place the above code inside its click event handler.

3. Adjusting the Code: Make sure to replace `your_username`, `your_password`, and the file path in `SaveToFile` with your actual credentials and desired saving location.

By implementing these steps, you should be able to access the camera's API, retrieve the image, and save it to a specified folder upon clicking the button in your VB6 application.
