can you be more specific for first option? the code i am writing is as follows:
Dim report As New Doctormaster
Dim ms As System.IO.MemoryStream
ms = CType(report.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat), System.IO.MemoryStream)
Response.ClearHeaders()
Response.Clear()
Response.Buffer = True
Response.ContentType = "application/pdf"
Try
Response.BinaryWrite(ms.ToArray)
Response.End()
Catch err As Exception
Response.Write("< BR >")
Response.Write(err.Message.ToString)
End Try

Response.BinaryWrite(ms.ToArray)
Response.End()
I mean once you have the report in the ms object, you can save this stream to file on the server side instead of writing it out to the output stream of the Response object. And what you might need to do next is to emit the client side script to open the new window with a link pointing to the saved file.

The following is code to open a new window from code behind. Put this in the event handler for button click.
Dim strPop As String = "" & vbCrLf _
& "window.open('crystalreports.aspx','Report');" & vbCrLf _
& "" & vbCrLf
Page.RegisterStartupScript("Pop", strPop)

I have been asked to refine out corporate intranet (Asp.net with C# codebehind) and they have asked for more charts and visual components.
My question is "Is Dundas and DotNetCharting the only tools out there for this?" DotNetCharting is the less expensive of the two. But I wanted to check all my options before I commited to one.
Thanks

Try searching for your answer first... You know you are on a programming web site that does actually have this ability.

I am an employee at Dundas Software who would like to give you my opinion on our product and the others. First, I’d like to answer your question, “Is Dundas and DotNetCharting the only tools out there for this?” Dundas and DotNetCharting are not the only component vendors. There are many companies that offer this type of tool and each with varying degrees of features and quality. .Now I’d like to talk about what things, in my opinion, are important in DV components.
The things I look for in a DV component are the following:
1) Time Investment / developer productivity
2) Robust Databinding
3) Performance \ Rendering speed
4) Visual Appeal
5) Intangibles (Tech Support, new releases)
Time Investment / developer productivity
Dundas Charts is not the easiest charting tool to use due to its extensive object model; we provide so many features that its hard to keep it simple. However, we do provide productivity helpers such as:
1) A chart wizard that sets you up with a visually appealing, databound chart in a matter of minutes.
2) Chart templates to ensure a constant look and feel across all your applications
3) An extensive sample set that provides code for you to re-use
4) Additional classes such as, Six Sigma and High \ Low Pass Filters, from our support site (http://support.dundas.com) to expand your charting experiences
5) Full integration into Visual Studio 2003 and 2005; after installation, the product appears in the Visual Studio Toolbox
Robust Databinding
This is the most important aspect of a DV component; after all, this is what charts are about. I want to be able to connect easily to various data types provided by VS Studio, e.g SqlDataReader, DataSet, DataTable, etc. It should be as simple as defining the data and then bind it directly to the chart, specifying what the X values and Y (or multiple Y) values are. Dundas Charts offers so many ways to bind to data; in fact, anything that implements the IEnumerable interface can easily be bound to the Chart.
Performance \ Rendering Speed
This is critical when vast amounts of data need to be populated into a chart over the Internet. Who wants to wait more than 5 seconds for a web based dashboard to be displayed? Dundas Charts was able to render about 170 charts per second on an AMD 64bit machine. Of course the complexity of the chart (e.g. color gradation, chart type) will affect the performance. What’s great about Dundas Charts is its proprietary FastLine algorithm made specifically for rendering large amounts of data points (hundreds of thousands of data points!) at break neck speeds. In our newest release, Dundas Charts 5.5, we are introducing FastPoint, as well.
Visual Appeal
Although the products mentioned above all do a fairly good job in regards to appearance. I would strongly recommend checking out our online dashboard demos at http://www.dundas.com/Dashboards/Samples.aspx, as well as our othter online galleries that can be found there.
Intangibles
The two most important intangibles to look for in a product: technical support and new releases. I think we both agree that technical support is one of the most important intangibles and should be a huge factor in your decision. Dundas Software has the biggest technical support team out there. You can reach us by telephone and \ or email. We usually have a response for you right on the spot for most technical questions. The real advantage with our technical support staff is the presales help we offer. Before you even make a purchase, we’ll answer all your questions with regards to the product. If you feel you need a more in depth demonstration of our products, you can directly reach any of your tech support staff via telephone or email. If it’s a complex need, we can even write you a fully functioning sample demo.
New releases are important. It’s nice to know that the DV component that you purchase will always be updated with bug fixes and new releases. Dundas Charts releases about 3 new versions a year, jam packed with new features based on client requests and things we feel would help make the chart that much better. For example, in our Dundas Charts 5.5 release, which is coming out soon, we have a new scrolling and zooming feature for our ASP .NET version. Using AJAX, you can zoom in to certain areas of the chart and scroll the chart, all over the web!
Final Thoughts
There are a few DV component tools out there. It really comes down to which competitor fits your needs the most. My final recommendation is to download all those products and to judge the products for your self. As well, be sure to contact support so you can gauge the component provider’s commitment to helping you as a customer.

Hi,
I have a problem. In one of my Asp.Net application i have to open a new popup window without using javascript.
Is it possible and if yes How?

you can open a link in a new window
<a href="MyLink.html" target="_new">Open MyLink.html in a new window</a>
Downside is that you dont get any control over the settings such as menubars, scrollbars etc.

The correct target to use is "_blank".
If you use "_new" you will open a new window with the name "_new". If it's left open any following links to that target will open in that window and not a new window.

good to know... Ive always used _new - but then ive never targetted that name subsequently so never seen the behaviour you describe.

Hi all,
I am trying to reload a treeview from a given start node passed to the page by session.
I have the following code in my page_load event
if (Page.Session["NavStartNode"] != null)
{
oTopics.iTTop_PK_ID =
Convert.ToInt32(Page.Session["NavStartNode"]);
oTopics.SelectOne();
LoadRoot(oTopics.sTTop_Name.ToString(), Page.Session[
"NavStartNode"].ToString());
tvMain.Nodes[0].PopulateOnDemand =
true;
}
The Loadroot sub is creating the root node and is working fine, but It does not take in consideration the "OnTreeNodePopulate" function. The node created does not have and child node and can't be expanded ...
This is driving me mad, please help. 
|
|
|
|
|
After setting the PopulateOnDemand property of the root node, you can try to expand the node with the Expand method:
...
tvMain.Nodes[0].PopulateOnDemand = true;
tvMain.Nodes[0].Expand();
}

Hi Dz
I have developed a site for online sale/purchase of Vehicles(cars,motorcycles,aircrafts,RVs,Heavy Equipment etc). I put a Search Box on top of each page for General Search in addition to Advance Search(Search by selecting Vehicle's category,Make,Model,Year of Manufecturing).
In General Search Customer can type search text like....
Ford(Make)
Ford Mustang(Make,Model)
2000 Ford Mustang(year,Make,Model)
Ford Mustang 2000(Make,Model,Year)
Mustang 2000(Mdel,Year)
2000 Mustang(Year, Model)
Harley Davidson Ultra Classic(Make,Model)
Now I need suggestions that how I can I make my General Search more more efficient so that I can get only relevent records as well as dont miss any record matching criteria.
Note: I am using MySQL at backEnd with ASP.net(VB.net)
Thanks in advance
Lets work it Out.........!
|
|
|
|
|
SELECT Make, Model, Year
FROM MyVehicleTable
WHERE Make Like '%' + @generalSearchCriteria + '%'
OR Model Like '%' + @generalSearchCriteria + '%'
OR Year Like '%' + @generalSearchCriteria + '%'
I forget if you use parameters with @-symbol in MySQL; it may be something else, but hopefully you get the suggestion.

Use the Replace method to replace the decimal comma to a period. Use double.Parse or double.TryParse to parse the string to a number, and the ToString method with the format string "n2" to format it with two decimals.
---
b { font-weight: normal; }
|
|
|
|
|
use String.format({f:2},var) to get the decimal values to 2 digits.

Thanks!!! now it's working fine!!!
