Hi,

I am developing an application to catalog your comic collections. In the comic info form I thought I would add an image drop utility so the user can add images from the comic into the comic's details. I thought it was working fine, but it seems it is not. So, this comic info form is opened from the main form. Then it has a tab control with different tabs. The one I'm interested in is the Images tab. I have set the AllowDrop property of all of them to true. The control I want to drop the images in is a FlowLayoutPanel that i have called flpImages. Finally, I am running Windows Vista Ultimate.

The code for the two events (DragOver and DragDrop) is the following:

private void pbImages_DragOver(object sender, DragEventArgs e)
{
try
{
if (e.Data.GetDataPresent(DataFormats.FileDrop) && (e.AllowedEffect & DragDropEffects.Copy) != 0)
e.Effect = DragDropEffects.Copy;
}
catch
{
System.Diagnostics.Debugger.Break();
}
}

private void pbImages_DragDrop(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop))
this.AddImages((string[])e.Data.GetData(DataFormats.FileDrop));
}

The AddImages code (although it never gets there)

private void AddImages(string[] filenames)
{
try
{
this.Cursor = Cursors.WaitCursor;
string destPath = Application.StartupPath + "\\Temp\\";
if (!Directory.Exists(destPath))
Directory.CreateDirectory(destPath);
foreach (string file in filenames)
{
// Create new picturebox to hold the image
PictureBox pb = new PictureBox();
pb.Width = 60;
pb.Height = pb.Width * pbImgDisplay.Height / pbImgDisplay.Width;
pb.BorderStyle = BorderStyle.FixedSingle;
pb.Name = "pbImage_" + (this.flpImages.Controls.Count + 1).ToString();
pb.Click += new EventHandler(this.pbImages_Click);

// Add the image to the new picturebox
// Get the image the user opened
Image theImage = Image.FromFile(file);
if (theImage.Width > theImage.Height)
theImage.RotateFlip(RotateFlipType.Rotate90FlipXY);
// Break the file name to get the image extension
string[] pieces = file.Split(Convert.ToChar("."));
double scale = 0;
// Since the image's size we want is the large picture box size, we save the image in that size in the temp
// folder first.
if (theImage.Width > this.pbImgDisplay.Width || theImage.Height > this.pbImgDisplay.Height)
{
scale = Math.Min((double)this.pbImgDisplay.Width / (double)theImage.Width, (double)this.pbImgDisplay.Height / (double)theImage.Height);
theImage = theImage.GetThumbnailImage((int)Math.Round(theImage.Width * scale, 0), (int)Math.Round(theImage.Height * scale, 0), null, (IntPtr)0);
}
string img = destPath + "temp_img_" + (this.flpImages.Controls.Count + 1).ToString() + "." + pieces[pieces.Length - 1];
theImage.Save(img);

// Now we need to create the thumbnail for the smaller picbox.
if (theImage.Width > pb.Width || theImage.Height > pb.Height)
{
scale = Math.Min((double)pb.Height / (double)theImage.Height, (double)pb.Width / (double)theImage.Width);
theImage = theImage.GetThumbnailImage((int)Math.Round(theImage.Width * scale, 0), (int)Math.Round(theImage.Height * scale, 0), null, (IntPtr)0);
}
img = destPath + "temp_thumb_" + (this.flpImages.Controls.Count + 1).ToString() + "." + pieces[pieces.Length - 1];
theImage.Save(img);
pb.ImageLocation = img;

this.flpImages.Controls.Add(pb);
this.imagesDescription.Add(String.Empty);
}
this.tabImages.Focus();
this.pbImages_Click(this.flpImages.Controls[this.flpImages.Controls.Count - 1], new EventArgs());
this.Cursor = Cursors.Default;
this.btnRemoveImage.Enabled = true;
this.tbImageNotes.Enabled = true;
}
catch (Exception exc)
{
MessageBox.Show("Error Adding the Image File.\n\n" + exc.Message);
}
}

All I get is an icon that indicates that nothing can be dropped (the forbidden icon) and can't drop anything. Can anyone help?

try this

private void pbImages_DragOver(object sender, DragEventArgs e)
{
// I delete the if condition because you didnt post what type of data you're dragging. But this will work on every type of data
e.Effect = DragDropEffects.Copy;
}

What dragging code? I only have two event handlers the DragOver and the DragDrop that I placed in the original message. The files are coming from outside the application, not from within the application.

oh okay. Here is a code that I used once.

private void Main_DragEnter(object sender, DragEventArgs e)
{
    e.Effect = DragDropEffects.Copy;
}
private void Main_DragDrop(object sender, DragEventArgs e)
{
    string[] DroppedFilesNames = (string[])e.Data.GetData(DataFormats.FileDrop);
    if (Path.GetFileName(DroppedFilesNames[0]) != "carcols.dat")
        MessageBox.Show("Wrong file.", Application.ProductName);
    else
        openFile(DroppedFilesNames[0]);
}

The problem was not in the code, it is with Windows Vista and UAC. Somehow Vista does not allow lower security files to be dropped on higher security controls and since Visual Studio 2008 had to be ran with Administrator priviledges, it was not allowing to drop the files. I have had to disable UAC and it works fine.

Hi,

when a PDF file is opened on IE, the PDF can be obtained in temporary internet files, how can I replace that file with other file of same file name.

I got the path of pdf file through this link
http://theagussantoso.blogspot.com/2008/11/get-temporary-internet-explorer-files.html
using c#, the file is not getting replaced with the instruction
File.Replace(sourceFileName, destinationFileName, destinationBackupFileName);

but the destinationFile is obtained in destinationBackupFile.

what may be the problem?
can anybody help me?

The file is in use, and you can't replace things that are in use. In other words, if you're drinking a beer, then it's impossible for me to replace the glass that you're using to hold that beer.

Web Control Issue - c#

rohithnair18-Mar-09 0:34

Hello friend,

I am using axWebBrowser to open a web page from c#.

I just used the control by placing the control in a form and on loading i have maximized the form and control will be dock fully in form.

I just used my personal email to open in this control. So that i have used userID and password along with code.

So once i run project it will open my inbox!!!

Now i just did some another way like once i minimize this need to move in to tray part with an icon...

So now i faced a problem...

I can minimize it in to tray and while im restoring from there the form is blank..

So i wondered. I had checked the issue regarding with resize property of the control.

Once i re size the form after loading everything, means if i stretch back the window in some other size, the loaded page gone off , but it will come after some time.

I dnt know whether its the issue regarding the cookie or resize issue..

This will work fine,if i minimize it in to task bar.

Any idea regarding this?

Regards
Rohi

Can't you just use a regular textbox, and set it to use a suitable dotmatrix font?

It can be done using RichTextBox and use a font like that one. In RTB, you can change particular text color.

NHibernate: getting the available row count while using maxResults

buchstaben17-Mar-09 23:30

Hi,

I've done some hibernate work querying data from oracle. Since the return might be a very huge list of objects, I use the SetMaxResults() method.

int maxDS = 1000;
ISession session = //..
ICriteria criteria = session.CreateCriteria(typeof(Trade));
criteria.SetMaxResults(maxDS);
AddCriterions(criteria); // I add some criterions in this method        
IList<Trade> trades = criteria.List<Trade>();

How can I get the number of totally available objects (for my criterions) without disposing maxDS and loading them all?

Thanks in advance.

I've found the solution:

criteria.SetProjection(Projections.RowCount());
int totalRecordsFound = (int)criteria.UniqueResult();

You need to find someone who will act as a gateway for sending sms. then they will have a API or example you can use.
