You need some kind of component on your form that can understand that file format and draw it. I don't know of any. You may have to get with the manufacturer of the drawing programs that generate those files to see if they have a component, or can recommend one.

Crystal Reports 8.5 to email a batch of reports

I am using Crystal Reports 8.5 to email a batch of reports. Destination property is set to 3. I am seeing the Export Options dialog box for Page Range for each report being emailed. This could be in the hundreds so I do not want to respond OK to the Export Options each time. Looking for an Active X control property to disable this Export Options dialog box. I have tried setting the ProgressDialog to False but it didn't make a difference. The Export Options box still popped up each time.

It's very urgent. Plz help me.

Hello

I have extracted the html code from a web table embedded in a Word document and stored it in a variable string as shown below. The Word document is saved as an html page in Word.

Dim html_string as String
html_string = ActiveDocument.HTMLProject.HTMLProjectItems(1).Text
Selection.WholeStory
Selection.Delete Unit:=wdCharacter, count:=1
Selection.TypeText Text:=html_string  '''LINE 5 is the problem line

It works very well when I test the script on Word documents with small embedded html tables with few rows and columns but not everything gets stored for large tables beyond a certain number of rows and columns. The string gets truncated after some point. The truncation seems to take place when I execute line 5 above (Selection.TypeText Text:html_string). The "html_string" variable itself retains all of the html code when I throw it's output to the screen so I know for a fact something is happening when I place the contents into the active Word document using the Selection.TypeText method. Is there a character size limit when using the Selection.TypeText method? If so, is there a way around this?

Thanks

Arial, Verdana.. What's slow, is it the generating of the report, or the actual physical printer?

Is it faster when you print from Microsoft Word or Internet Explorer? It might very well be that the physical printer can't process the requests faster.

Try another font, and see if the problem persists. This may be due to the font-setting (printing in bold) or the print-quality setting (high quality?)

It's hard to diagnose the problem based on a short description.

It is very, very unlikely that the font used would make your printing slow. Unless you are trying to do everything in Italic or Bold for a font that doesn't include those styles, and AFAIK TimesNewRoman does include them, so that ain't the cause of your problem.

If you have a slow printer, then you have a slow printer. On the oter hand if it prints OK from Word or other apps, then there's only one possible cause - your code.

Unless you post the part of your code that deals with the printing, it is very unlikely that anybody can really help you. If you do decide to post it DO NOT POST ALL OF IT, just the printing part(s). Smile | :)

datatable from datasource

Hello,

I would like to obtain a datatable from a datasource of a gridview :

Dim Table As DataTableCollection = DsGrid.Tables
                BindSource.DataSource = Table(0)
                BindSource.Filter = "Nom LIKE '" & SearchNom & "'
Me.DataGridViewVisiteur.DataSource = BindSource                
                Dim dt as datatable = CType(Me.DataGridViewVisiteur.DataSource, DataTable)

I am getting this message :

Unable to cast object of type 'System.Windows.Forms.BindingSource' to type 'System.Data.DataTable'.

How can i do this ?
Thanks

I assume it is the last line that is giving the error?

If you would give a description of what it is that you are trying to do, it might help. And I don't mean "i am trying to get a datatable from a gridview to use as a datasource for another gridview" I mean "I am trying to use two gridviews from the same datasource but apply a filter to only one of them".

I would like to obtain the data that are stored in the datagridview.

Re: datatable from datasource

Henry Minute2-Jul-09 3:58

2-Jul-09 3:58

There are two ways that occur to me:

1) you already have the data in Table so you could use Dim dt as datatable = Table(0)
2) alternatively you could use the DataRowCollection of either DsGrid or DataGridViewVisiteur

If these do not suit your needs then I hope that someone else is able to help you. Smile | :)

The problem is : i give table(0) to my datagrid, and then i use filter on it.
I want to get back the filtered data remaining in my grid.
Table(0) -> contains all data
i apply a filter using a BindSource.Filter .
I want to get back the filtered data ( those on my datagrid view)
How can i do this ? is it possible ?

Henry Minute2-Jul-09 5:17

The only way I know is to use the Rows property of the DataGridView that displays the filtered data. This is a collection of DataGridViewRow

Take a look at the documentation for any of those terms for examples of how to use them.

There may be other ways of doing what you want, but both of the BindingSources still access the unaltered data. The filtered one just outputs a filtered sub set to the DataGridView.

ListView doubleClick wont fire

Chana Winkler1-Jul-09 22:48

Hi all, it's my first time in this forum, I hope you can help.
I have a listview that displays a list of PDF files. When the user clicks on a row (in the "selectedIndexChanged" event), I display the selected PDF underneath the Listview in a Webbrowser control

WebBrowser1.Navigate(sFile)

So far so good.
Additionally, when the user double clicks a row on the ListView (in the "DoubleClick" event), I use

Process.Start(sFile)

where sFile is the name of the PDF file, to open Adobe Acrobat Reader in a separate process.
Now here's the problem: This only works when the user double clicks the currently selected row. If however, the user double clicks on a row that is not selected in the list view, the application produces two "SelectedIndexChanged" events, and no double click event.
What I've discovered is that if I comment out the line

WebBrowser1.Navigate(sFile)

then my code works as expected. A single click produces a "selectedIndexChanged", a double click produces a "selectedIndexChanged" and a "DoubleClick".
So it seems as if calling WebBrowser1.Navigate(sFile) somehow interrupts the events from firing correctly.
Any ideas on how I could solve this issue?
Thank you.

Chana

The first thing that comes to mind is, to make a comparison in the SelectedIndexChanged event. When, with the double click, the SelectedIndexChanged event is fired the second time, check to see if the selected index remains the same.

When the SelectedIndexChanged event is fired, and the selected index remains the same, you execute Process.Start(sFile) and otherwise WebBrowser1.Navigate(sFile).

My advice is free, and you may get what you paid for.

Thank you for your answer. I tried it out, it wasn't exactly what I needed because I would have had to put in a timer to see whether the two clicks came close together etc.
I did find a different workable solution though. ListView has an "activated" attribute, which, when set to "Two Clicks" activates the selected row on the listview in two clicks. This differs from "DoubleClick" because "Two Clicks" allows for some time to elapse between the two.
I put the Process.Start(sFile) into the ListView1_ItemActivate() event and voila! It works!

Prevent other app's I/O

Hi
My program should prevent certain processes' IO operations, and only perform them if the user clicks Yes in a Yes/No dialog. Can this be done?

And anyway how can I check wether those processes are running?
Probably there is an API or sg for that, but I'm new to this part of programming.

Much thanks in advance Smile | :)

Not that I'm aware of. You could try and modify the security-attributes of the file, taking away or granting the read/write rights. You'd have to know in advance what file is going to be edited.
