. Net language APP development platform-Smobiler Learning Log: quick implementation of the image upload function on the mobile phone.
First, scycler is a development platform that uses the. Net language to develop apps in the VS environment. It may be more convenient than Xamarin. 1. Target Style
The following operations are required to achieve the effect:
1. Drag a ResourceUploader control and an ImageButton control from "scycler Components" on the toolbar to the form interface.
2. Click Event of ImageButton
VB:
Private Sub imageButton1_Click(sender As Object, e As EventArgs)Handles imageButton1.Click
resourceUploader1.Show()
End Sub
C#:
private void imageButton1_Click(object sender, EventArgs e)
{
resourceUploader1.Show();
}
3. Modify the attributes of the ResourceUploader control a. MaxSelectCount
Sets the maximum number of resources to be uploaded at a time. The default value is "9". A maximum of 9 images can be uploaded at a time;
B. QualityMode attributes
Obtains or sets the upload quality mode of the camera component. The default value is "Custom", indicating that both compression and source Image Upload are supported. 2;
If this attribute is set to "Compressed", it indicates that only the upload can be Compressed;
If this attribute is set to "Original", only the source image can be uploaded;
C. Uploading event
VB:
Dim imglist As List(Of String) = New List(Of String)
Private Sub resourceUploader1_Uploading(sender As Object, e As BarcodeData)Handles resourceUploader1.Uploading
Try
If e.IsError = False Then
e.SaveFile()
imglist.Add(e.ResourceID)
getImg()
End If
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
C#:
private List<string> imglist = new List<string>();
private void resourceUploader1_Uploading(object sender, BinaryData e)
{
try
{
if (e.IsError == false)
{
e.SaveFile();
imglist.Add(e.ResourceID);
getImg();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
Note: Call the ResourceUploader control to obtain images.
D. Other code
VB:
Private Sub resourceuploader1_ImageCaptured(sender As Object, e As BarcodeData)Handles resourceuploader1.ImageCaptured
If imglist.Count > 0 & imglist.Count <= 9 Then
For i = 0 To imglist.Count Step 1
Select Case i
Case 1
img1.Visible = true
btndelimg1.Visible = true
img1.ResourceID = imglist(i - 1)
img1.Refresh()
Case 2
img2.Visible = true
btndelimg2.Visible = true
img2.ResourceID = imglist(i - 1)
img2.Refresh()
Case 3
img3.Visible = true
btndelimg3.Visible = true
img3.ResourceID = imglist(i - 1)
img3.Refresh()
Case 4
img4.Visible = true

img4.ResourceID = imglist(i - 1)
img4.Refresh()
Case 5
img5.Visible = true

img5.Refresh()
Case 6
img6.Visible = true

img6.ResourceID = imglist(i - 1)
img6.Refresh()
Case 7
img7.Visible = true
btndelimg7.Visible = true
img7.ResourceID = imglist(i - 1)
img7.Refresh()
Case 8
img8.Visible = true
btndelimg8.Visible = true
img8.ResourceID = imglist(i - 1)
img8.Refresh()
Case 9
img9.Visible = true
btndelimg9.Visible = true
img9.ResourceID = imglist(i - 1)
img9.Refresh()
End Select
Next
End If
End Sub
C#:
private void getImg()
{
if (imglist.Count > 0 & imglist.Count <= 9)
{
for (int i = 1; i <= imglist.Count; i++)
{
switch (i)
{
case 1:
img1.Visible = true;
btndelimg1.Visible = true;
img1.ResourceID = imglist[i - 1];
img1.Refresh();
break;
case 2:
img2.Visible = true;
btndelimg2.Visible = true;
img2.ResourceID = imglist[i - 1];
img2.Refresh();
break;
case 3:
img3.Visible = true;
btndelimg3.Visible = true;
img3.ResourceID = imglist[i - 1];
img3.Refresh();
break;
case 4:
