If your requirement is just opensource without emphasizing on asp.net, I would suggest even Horde IMP. It is in PHP and has good features.

Hi,
I am trying to preview the individual pages found inside a multipage TIFF file as thumbnails using PictureBoxes on an ASP.NET aspx page.
Microsoft Office Document Imaging 12.0 (MODI) - is the release which came with Office 2007.
What I am trying to do is split a mulit-page TIFF file using MODI into single pages. Once I've got the pages, I want to show the individual page's thumbnail in a PictureBox in an ASP.NET aspx page.
At the same time I want to OCR the individual pages, as I am using the text found inside each page - which is why I am using MODI.
Using MODI to split the TIFF file seems to work fine - and I can OCR each page and count the words, etc.
Here is the code which does that:
MODI.Document objDoc = new MODI.Document();
//strFileName below is a string variable pointing to the file location of a TIFF file
objDoc.Create(strFileName);
objDoc.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true);
int nWordCount = 0;
int nPageCount = objDoc.Images.Count;
string strOCR = "";
//Now I cycle through each page (which is an image)
for (int x = 0; x < objDoc.Images.Count; x++)
{
MODI.Image objImage = (MODI.Image)objDoc.Images[x];
//At this point I want to extract the thumbnail property from the objImage using something like this:
//pictureBox1.Image = ConvertToImageFromIPictureDisp( objImage.get_Thumbnail(MODI.MiTHUMBNAIL_SIZE.miTHUMB_SIZE_LARGE));
MODI.Layout objLayout = objImage.Layout;
//to get a specific word, you can get it at an index, for instance word number 5:
//MODI.Word word = (MODI.Word)objLayout.Words[5];
//I want all words
nWordCount += objLayout.Words.Count;
for (int i = 0; i < objLayout.Words.Count; i++)
{
MODI.Word objWord = (MODI.Word)objLayout.Words[i];
strOCR += objWord.Text;
}
}
objDoc.Close(false);
So at this point, you have OCR'ed the entire TIFF file, and the variable strOCR will have your text with which you can do what you want.
The problem I am getting and with which I am trying to find some help, is that in the same piece of code above, I want to add a piece to extract the thumbnail of each image (page).
So inside the for x loop just after MODI.Image objImage = (MODI.Image)objDoc.Images[x];
I want to extract the thumbnail using this piece of code:
objImage.get_Thumbnail(MODI.MiTHUMBNAIL_SIZE.miTHUMB_SIZE_LARGE)
get_Thumbnail returns of type IPictureDisp (add a reference to stdole to access this interface)
A PictureBox's image property is of type System.Drawing.Image
So how do I convert my IPictureDisp to an Image so that I can use it in a PictureBox?
I've tried to use a class (which inherits from System.Windows.Forms.AxHost) with the following method:
public static System.Drawing.Image ConvertIPictureToImage
(stdole.IPictureDisp picture)
{
return (System.Drawing.Image)System.Windows.Forms.AxHost
.GetPictureFromIPictureDisp(picture);
}
but the exception I get is this: Unknown name. (Exception from HRESULT: 0x80020006 (DISP_E_UNKNOWNNAME))
So I am stuck at this point.
Has anybody come across this and do you perhaps know how to resolve this issue?
Cheers

I want to use an AJAX control on an ASP Net page. The setup instructions require a path to my cache directory. What's required in setting up a cache directory?
PJ

Which setup instructions are you talking of?
Never heard of a cache directory in conjunction with AJAX (I'm using ASP.NET Ajax).

One of the php files has the following lines of code. I don't know what path I should put in here '$rss->cache_dir = ? '. I've copied in the instructions below.
header('Content-type: text/xml');
// include lastRSS
include "lastRSS.php"; //path to lastRSS.php on your server from this script ("bridge.php")
// Create lastRSS object
$rss = new lastRSS;
$rss->cache_dir = 'cache'; //path to cache directory on your server from this script. Chmod 777!
$rss->date_format = 'M d, Y g:i:s A'; //date format of RSS item. See PHP date() function for possible input.

I have Drop down list below the calendar popup
My Problem is My Popup not shown over the drop down list
It works in mozilla and fails to work in IE6
I tried Z-index properties but not doing well
Is There any solution
swapnil

Yeah this is a fairly well known bug in IE. Root cause is that IE uses lightweight controls, except for drop down lists, which always render on top.
You can get around this by sticking an empty iframe in the item that pops up, width and height 100% but given a z-order to make it at the bottom. This works because the iframe ends up being rendered after the drop down list, forcing all the controls that are higher than the iframe to the top.
Bit dodgy though, and I've never really liked it. The other option I've seen uses js to hide the drop down lists when the calendar / menu pops up. :/

Hello All,
I am having a webform with two textbox and and one dropdownlist .. and one gridview
when i entered values in textbox and select dropdownlist value after that i click on save button then it will save in database.
and the display the textbox value and dropdownlist selected value in GridView what i taken in the same page .
The following code i wrote for in codebehind:
protected void Save_Click(object sender, EventArgs e)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Mfund_String"].ConnectionString))
{
con.Open();
SqlCommand cmd = new SqlCommand("insert into mfund_share_dtls values(" + this.TextBox1.Text + ",'" + this.ddlFund_name.SelectedItem.Value + "','" + this.ddlDOBdd.SelectedItem.Value + '-' + this.ddlDOBmm.SelectedItem.Value + '-' + this.ddlDOByyyy.SelectedItem.Value + "'," + this.txtNoUnits.Text + "," + this.txtPricePaid.Text + ")", con);
cmd.ExecuteNonQuery();
SqlCommand cmd1 = new SqlCommand("SELECT fund_no, usr_no, fund_name, dop, no_units, price_paid FROM mfund_share_dtls WHERE(usr_no = " + this.TextBox1.Text + ") AND (fund_no =(SELECT MAX(fund_no) AS Expr1 FROM mfund_share_dtls AS mfund_share_dtls_1 WHERE(usr_no = " + this.TextBox1.Text + ")))", con);
SqlDataReader dbdr = cmd1.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(dbdr);
dbdr.Close();
GridView1.DataSource = dt;
GridView1.DataBind();
}
}
So now i want in gridview edit... suppose the client mistakenly chosen wrong dropdownlist value and enterd wrong textbox value,
so now he want to edit the dropdownlist value and textbox value in gridview.
How i have to approach for gridview update through code behind and please guide me ...i need to display the dropdownlist also to select correct dropdownlist value in gridview update.
Many Thanks
Vijay

Use Template Column in DataList control. Put the LinkControl in that template column.
OR
<a href="http://mysite/anotherpage.aspx?id=1" > <%# DataBinder.Eval(Container.DataItem,"fieldName") %></a>

Okay. Lets debug the application..
Let's say we have two pages called page1 and page2. We will divide the issue into small pieces ~
1. Using static data in page1
2. Retrieving the data in page2
3. Checking whether the SQL statment is correct or not
4. Changing static data to dynamic data in page1.
1. Using static data in page1
We will remove all dynamic value in A link to avoid NULL value and "".
Note: dynamic value means <%# DataBinder.Eval(Container.DataItem,"AD_TYPE") %>.
<a href="http://localhost/approvedplotfinal/classified/page2.aspx?li=<%#DataBinder.Eval(Container.DataItem,"AD_TITLE") %>,type=<%# DataBinder.Eval(Container.DataItem,"AD_TYPE") %>,price=<%# DataBinder.Eval(Container.DataItem,"PRICE") %>"><br />
<%# DataBinder.Eval(Container.DataItem,"AD_TITLE") %><br />
</a><br />
We will replace all dynamic value with all static value.
<br />
<a href="http://localhost/approvedplotfinal/classified/page2.aspx?li=mytitle&type=mytype&price=100" ><br />
<%# DataBinder.Eval(Container.DataItem,"AD_TITLE") %><br />
</a>
Run the application to check whether there is any error or not.
2. Retrieving the data in page2
Forget about other code in page2. We will assume that we have only the following lines in Page Load.
search=Request.QueryString["li"].ToString();
type1=Request.QueryString["type"].ToString();
price=Request.QueryString["price"].ToString();
- Set the breakpoint at "search" variable.
- Run the application. (Page1 is start-up page)
- Click the link in page1. (it will take you to page2.)
- Check whether "Request.QueryString["li"]" is null or not.
- Check whether "Request.QueryString["type"]" is null or not.
- Check whether "Request.QueryString["price"]" is null or not.
Note: All three parameters should not be NULL. If you are getting NULL then let me know.
3. Checking whether the SQL statment is correct or not
Which Database are you using? If it's SQL Server, you don't need "&&".
string sstr="select * FROM ads where AD_TITLE='"+search+"'&& AD_TYPE='"+type1+"' && PRICE='"+price+"' ";<br />
So, we will change something like that.
string sstr="select * FROM ads where AD_TITLE='" + search + "' AND AD_TYPE = '" + type1 + "' AND PRICE='"+ price + "'";<br />
- Check this variable "sstr" in Quick Watch or Immediate Window.
- Copy the string from Quick Watch or Immediate Window.
- Paste in Query Analyzer and Run it.
(You should not get any error. this is about checking whether the SQL statement is correct or not.)
4. Changing static data to dynamic data in page1.
It is still working fine. we will remove the static code in page and replace with dynamic code.
So, the following code will be used again..
<a href="http://localhost/approvedplotfinal/classified/page2.aspx?li=<%#DataBinder.Eval(Container.DataItem,"AD_TITLE") %>,type=<%# DataBinder.Eval(Container.DataItem,"AD_TYPE") %>,price=<%# DataBinder.Eval(Container.DataItem,"PRICE") %>"><br />
<%# DataBinder.Eval(Container.DataItem,"AD_TITLE") %><br />
</a><br />
- Run the application
- Click the link in page1.
- Check the Request.QueryString and SQL Statement in page2.
if it's working until now, you are done..
Please follow the step as I mention here.. let me know the result..
Thanks and Regards,
