我用的是VS.NET 2005
在这中情况下不能改变,在调试时已经看到这一行以通过,就好想处理了也没反应:
this.BackgroundImage = back_error;========================================
private void txtCommand_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == 13)
{
try
{
System.Diagnostics.Process.Start(txtCommand.Text);
}
catch(Exception ex)
{
justError = true;
this.BackgroundImage = back_error; txtCommand.Text = txtCommand.Text + " --*" + ex.Message + "*--";
}
}
}
================================================但这中情况就有,可以看到背景改变了:================================================
private void txtCommand_KeyPress(object sender, KeyPressEventArgs e)
{
this.BackgroundImage = back_error; if (e.KeyChar == 13)
{
try
{
System.Diagnostics.Process.Start(txtCommand.Text);
}
catch(Exception ex)
{
justError = true;
txtCommand.Text = txtCommand.Text + " --*" + ex.Message + "*--";
}
}
}
================================================到了这种又没有了(真搞不明白):================================================
private void txtCommand_KeyPress(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == 13)
{
try
{
System.Diagnostics.Process.Start(txtCommand.Text);
}
catch(Exception ex)
{
justError = true;
txtCommand.Text = txtCommand.Text + " --*" + ex.Message + "*--";
}
} this.BackgroundImage = back_error;
}
============================================请各位帮小弟看看这是个什么问题,先谢了!!
