Hello,
i have an application with signature form...
{
private Bitmap bitmap; private bool hasCapture; private int oldX = 0; private int oldY = 0; private Pen ipen = new Pen(Color.Red); public Form1(){
InitializeComponent();
}
private void panel1_Paint(object sender, PaintEventArgs e){
e.Graphics.DrawImage(
this.bitmap, 0, 0 );}
private void panel1_MouseDown(object sender, MouseEventArgs e){
hasCapture =
true;oldX = e.X;
oldY = e.Y;
}
private void panel1_MouseMove(object sender, MouseEventArgs e){
int x, y; if (hasCapture){
x = e.X;
y = e.Y;
Graphics.FromImage(bitmap).DrawLine(ipen, oldX, oldY, x, y);panel1.Invalidate(
new Rectangle(Math.Min(x, oldX), Math.Min(y, oldY), Math.Abs(oldX - x) + 1, Math.Abs(oldY - y) + 1));oldX = x;
oldY = y;
}
}
private void panel1_MouseUp(object sender, MouseEventArgs e){
hasCapture =
false;}
private void Form1_Load(object sender, EventArgs e){
bitmap =
new Bitmap(240, 147, System.Drawing.Imaging.PixelFormat.Format24bppRgb); Graphics.FromImage(bitmap).Clear(Color.White); this.firmaTableAdapter.Fill(this.firmaDataSet.Firma);}
private void button1_Click(object sender, EventArgs e){
FirmaDataSet.FirmaRow fr = firmaDataSet.Firma.NewFirmaRow();fr[
"firma"] = ConvertImageToByteArray(bitmap, System.Drawing.Imaging.ImageFormat.Bmp);firmaDataSet.Firma.Rows.Add(fr);
firmaTableAdapter.Update(firmaDataSet.Firma);
}
private byte[] ConvertImageToByteArray(System.Drawing.Bitmap imageToConvert, System.Drawing.Imaging.ImageFormat formatOfImage){
byte[] Ret; try{
using (System.IO.MemoryStream ms = new System.IO.MemoryStream()){
imageToConvert.Save(ms, formatOfImage);
Ret = ms.ToArray();
}
}
catch (Exception ex) { throw; } return Ret;}
}
but i have a problem, in some PPC it works good and in some it doesnt work...
