Can Crystal Report show dynamic picture?
Is anyone know?
thank you
|
|

Use a typed DataSet, put the graphic in the DataSet and use the DataSet as DataSource for the Crystal Report.
So we can make it as Dynamic.
Hope this will help you.

Hi, I've found the function below when I was searching for ways to prevent SQL Injection. Basically it is supposed to remove the words select, drop, inser, delete, and other characters that can affect your database. I'm new to VB.NET and ASP.NET so please bear with me.
function killChars(strWords)
dim badChars
dim newChars
badChars = array("select", "drop", ";", "--", "insert", "delete", "xp_")
newChars = strWords
for i = 0 to uBound(badChars)
newChars = replace(newChars, badChars(i), "")
next
killChars = newChars
end function
I get the error message "array is a type and can not be used as an expression". I also noticed that the datatype for the variables badChar and newChars were not specified and VS2003 says the variable "i" in the for loop was not declared. I have seen vb.net For loops used the way its being used in the function above without generating errors. Please help clarify, thank you in advance for your help.

If you want to prevent SQL injection attacks then don't accept SQL statements period, use store procedures or parameterized queries.

Use Stored Procedure.
Then you will not get these error.

LOL - yeah, I sometimes give an answer where the correct answer has been given, but I feel I can expand on it. Some people seem to just reiterate answers tho, some posts get 6 or 7 answers, all the same, hours apart. Go figure

Well - does the server have .NET 2.0 installed? Would seem like an obvious requirement to me....

I have ported my Visual Studio2003/asp.net 1.1 web application on to Visual Studio 2005/asp.net2.0 platform. One page of this web application behaves strangely. On the home page of the application there is a head control and footer control. This user controls have links which allows users to go to various pages upon clicking. All except one link somehow behaves differently. This link however upon clicking opens up correctly the page but on clicking any button or even doing selected item change on drop down box on the page displays error like “Internet Explorer cannot display the webpage” and under what you can try section it lists Diagnose Connection Problem and More Information. If I try to browse this site on development machine I get an error “The page can not be displayed” and “cannot find Server or DNS Error”. The server on which this web application is deployed is Virtual Machine having Windows 2003 sever with IIS 6.0 and asp.net 2.0 and .Net Framework 2.0.
Can any one please shed light how to solve this problem?
I would like to thank you in advance for your help.

The links point to the wrong URL. Check what url is in the browser address bar when you get these errors.

Thank you for your reply.
This error also occurs even while changing selection in drop down box.The same link works fine in Visual Studio 2003/asp.net 1.1 enviornment.

I have code that calls a report (report service 2005) that I have to put into a web service and then stream to a client app (vb - asp.net). The code that runs the report, gets and displays the report fine if I place it on a regular aspx page but I can't figure out how to put it in a web service and stream it to a client for consumption.
The following code will display the report:
Response.ClearContent()
Response.AppendHeader("content-length", result.Length.ToString())
Response.ContentType = "application/PDF"
Response.BinaryWrite(result)
Response.Flush()
Response.Close()
and this will write it to a file:
Dim stream As System.IO.FileStream = System.IO.File.OpenWrite(fileName)
stream.Write(result, 0, result.Length)
But how to I do this as a web method?????
Full code is below:

Hello, I'm new to ASP.NET. I 've ben a C# programmer for about a year, but I'm just touching on the realms of web development.
Anyhow... I'm having a problem. Everytime I try to compile and run my page, I get the following message: "CS0117: 'ASP.index_aspx' does not contain a definition for 'MyScript'"
This is the code on my page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<%@ Page Language="C#" %>
<html dir="ltr" xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Language" content="en-us" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Test</title>
<link rel="stylesheet" type="text/css" href="default.css" />
<script type="text/c#" id="MyScript">
private void MyFunc(object sender, EventArgs e)
{
TextBox1.Text = "Test";
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:Button runat="server" Text="Button" id="Button1" onClick="MyScript.MyFunc()"/>
<asp:TextBox runat="server" id="TextBox1" MaxLength="10" Rows="1" Columns="10"/>
</form>
</body>
</html>
If it helps any, I'm using Microsoft Expression Web, because I don't have anything else other than C# Express (No asp.net support)
I'd appreciate any help.

You need to add the runat=server attribute to your script tag
<runat="server"</b>>>
It is a better implementation to use a code behind file, htough I'm not usre if Expressions supports this. Why not use Visual Web Developer Express Edition?
<div class="ForumSig"><hr>only two letters away from being an asset</div>

Ha ha, thanks. I feel dumb.
And, Expressions "allows" codebehind, but doesn't "support" it. Now that I know there's a Visual Web Developer Express... I'm off to go find it!

I'd like to know if it is possible to not allow Shift Click to open in a new browser window. This is IE6.x I'm wondering about.
I haven't even begun to think IE 7.x yet.

I have a .DLL in my Project/App_code folder, it works without adding any import statements to my .aspx programs on local machine. But when I upload my web app, it says my DLL don't exist. What can I do, can anyone help me, I appreciate it.
|
|
|
|
|
the DLL is both in my project's /bin and /app_code directory and I receive this message.
Compiler Error Message: CS0103: The name 'Sel' does not exist in the current context.
|
|
|
|
|
I solved it, but was wondering If I can change the location of the DLLs, perhaps more local. I had to go up to the root and place my bin folder there. Can I put it in my project folder somehow?

Assuming this an assembly from another project, or third party, you need to add a reference to it in your application. That's all it should take.
