Finding a Memory Leak in ISAPI Extension

Turtle Hand25-Oct-04 9:24

25-Oct-04 9:24

I need some help finding a memory leak in an isapi extension I am maintaining. This extension leaks memory at a rate of 7mb every 5 minutes. I've been thru the Code Project article: Memory(-Leak) and Exception Trace (CRT and COM Leaks) by Jochen Kalmbach and it seems to be COM objects that are leaking. His approach doesn't work well with COM.

I've tried using UMDH.exe from MS, but am not able to set gflags for inetinfo.exe.

Any help at finding these leaks and/or using umdh.exe is appreciated.

Converting a text file to an RSS Feed

Here is the prodject that I'm working on. I have a phone system that produces a CDR file which is just a tab delimited text file showing all the incoming/outgoing calls. I need to convert this to a RSS feed. Right now I can link to the text file using the ODBC to text file link and I learned that I need to us a schema.ini file to make this approach work right. I also already have a XMLS file to format a wellformed XML file into the RSS file I need. My issue is I just don't know the best we to get the data into that first well formed XML file. I learned about something called ADODB.Stream but not sure if that is the way. http://support.microsoft.com/default.aspx?scid=kb;EN-US;q271620
Should I just use the Microsoft.XMLDOM? Any help to point me in the right direction would be great!

Custom cursor during Drag-drop

Does anyone know if it is possible to have a custom cursor during drag and drop in IE.

I have a some script-function-events asigned to an image object:
Simalar to the following:

<br />
	function handleMouseMove(e) {<br />
		if (!e) var e = window.event;<br />
		var elm = e.srcElement;<br />
		elm.dragDrop();<br />
	}<br />
	<br />
	function handleDragStart(e) {<br />
		// doing some stuff...<br />
	}<br />
	<br />
	function handleDraging(e) {<br />
		// doing a lot of stuff<br />
		// cursor is 'no-drop' don't want it to be.<br />
		// can not use "window.event.returnValue = false;" beacuse other stuff will stop work then.<br />
	}<br />
	<br />
	function handleDragEnd(e) {<br />
		// Doing stuff.<br />
	}<br />

So what I want is to asign an other cursor thatn the default 'no-drop' when draging the specified object (an image).

Thanks!

You will have to make subsequent HttpWebRequest calls for each resource you find in the HTML page. So parse for images, applets, CSS, JS etc. files and create a HttpWebRequest for each.

On my web site I have enabled spamasassin, using my own user_prefs file, but regardless of what I set the score to, once the event is triggered the score is always set in the email headers as 1, not 20 as in the example below.

Now is it me, or am I doing something wrong? Has anyone go this working with Spamasssassin 3.0.0?

<br />
  # Display all the scores<br />
add_header all tf Score Values (_TESTSSCORES(,)_)<br />
<br />
rawbody TF_RAWBODY_WARNING_1 /message\.scr/i<br />
score TF_RAWBODY_WARNING_1 20<br />

Hi All you need is to add the keyword desc

SELECTOR="SELECT * FROM MYTABLE WHERE MYDEF LIKE '%"& search &"%' ORDER BY MYDATE desc

Re: asp access

the default is ascend, you want to descend, just append the string "DESC"

thus your new SQL is:
SELECTOR="SELECT * FROM MYTABLE WHERE MYDEF LIKE '%"& search &"%' ORDER BY MYDATE DESC"

Thread Safety in Web Service

mterzich22-Oct-04 10:42

It appears that a Web Service thread is safe unless you either Thread.Sleep() or create a new thread. Is that correct? I was worried that a second client could enter a [WebMethod] while the first client was doing things such as working with Hashtables or the Registry (both of which are suppose to be very thread unsafe. Therefore I wrote the following two WebMethods below to check out whether the threads would switch if Test() was called by one client and test1() would be called by another and the threads didn't appear to switch. Test() loops for a long time (about 20 seconds) while creating 10 entries in a Hashtable and reading the Registry 10 times. Test1() should immediately return a value. I start Test() with one client and then immediately start Test1() with a second client and the second client doesn't return until the first client completes which makes me think that the threads are safe. If I place a Tread.Sleep(1) in Test(), the second client returns immediately indicating that the thread will switch with a Thead.Sleep().

[WebMethod]
public int Test()
{
Hashtable x;
RegistryKey RegKey;
string Value;
string Path;

x = new Hashtable();
for(int i=0; i<10; i++)
{
for(long l=0; l<300000000; l++)
{
}
x.Add(i, "1234567");
Path = "Software\\MyTest\\MyTest\\Net\\Configuration\\"+i.ToString();
RegKey = Registry.CurrentUser.OpenSubKey(Path, true);
if(RegKey == null)
{
try
{
RegKey = Registry.CurrentUser.CreateSubKey(Path);
}
catch (Exception e)
{
e = e;
return(0);
}
}
Value = Convert.ToString(RegKey.GetValue(i.ToString(), ""));
RegKey.Close();
}
return(5);
}

[WebMethod]
public int Test1()
{
return(1);
}

minimal padding/margin of a table in a page.

Maximilien21-Oct-04 9:39

I have a table as the sole element of a page, is there a way to have it as close as possible to the borders of the page ?

I can set the left margin to a negative value but that doesn't seem right :
{margin-left: -5px}

I'd like to have my table fit as much as possible the inside of the page "frame"; now, there's too much padding.

Thanks.

<table cellpadding="0px" cellspacing="0px">

Make sure you set margin: 0px in the body tag

Any good image editing components?

Does anybody know of a GOOD image editing component for webpages? I need at least the following functionality:

Pasting
Resizing
Cropping
Saving/uploading (to server)
.asp/.aspx supported

Other bonuses might include adding caption bubbles to the images, but is not critical.

Thanks

Feedback Form in Email

Hi,

I have been asked by our clients to create a customer feedback form which will be contained and distributed in an email. Once this form is submitted it will generate a reply email containing the form responses.

It's not something myself or any of my collegues have done before in ASP, so I'd like to know if it's possible first.

At the moment I have a test ASP script which sends a HTML form via email. The form action is set to post to another ASP script which will build a table of results and send back to our clients.

Thanks in advance.
