If you are using task manager to detect memory usage, what you are seeing is the programs working set and not the atuall memory usage.
You say you are using the Dispose method as you close windows. But do those child windows use any resources that are not automatically disposed?
Contrary to popular belief, .NET's automaticall memory management does not imply immediate 100% resource cleanup. Some resources have to be cleaned up manually to decrease memory footprint at any given time since the garbage collector funtions in a non-deterministic way.

I don’t have any other resources in them . say if I have 20 child windows even after I close all of them, Task Manager dose not reflect it , till I close the MDI main.
Is Task Manager showing the correct memory ?
Any other tool to track memory ?

How to Create a new Access database using C#?
i want create a new access database.i don't kown how to write the SQL expression.
and i want to kown is there other way to create a new database not use SQL language.beacause i kown there is ADOX in ado2.5 and it can create database.but i can't find anything can create database in ado.net.
thanks.

I'm interested in knowing too.
The only other technique I know, and have used before, is to embed a blank database into the assembly and write it out to file using a binary stream whenever a new database is needed. I know, its ugly and bad, but it works. Though if you want to be able to create for different Access versions you'd need to embed each one, which is even more ugly and bad.
Also, you can use Interop to access ADOX from C#.
|
|
|
|
|
I think you have to send SQL statement to Access. (CREATE DATABASE) You can do it in this way with ado.net.

Here's my ghetto xml (byteFile1.xml)...
<?xml version="1.0"?>
<Bytes>
<byte1>
<one>00</one>
<two>01</two>
<three>02</three>
<four>03</four>
<five>04</five>
<six>05</six>
<seven>06</seven>
<eight>07</eight>
</byte1>
<byte2>
<one>21</one>
<two>15</two>
<three>12</three>
<four>11</four>
<five>05</five>
<six>01</six>
<seven>08</seven>
<eight>04</eight>
</byte2>
<byte3>
<one>02</one>
<two>00</two>
<three>10</three>
<four>18</four>
<five>81</five>
<six>05</six>
<seven>06</seven>
<eight>07</eight>
</byte3>
</Bytes>
now here's the code I process it with...
int nOutNum;
XmlDocument xmlDoc=new XmlDataDocument();
XmlNode bit;
string NUM;
xmlDoc.Load("byteFile1.xml");
bit=xmlDoc.SelectSingleNode("//Bytes/byte1");
NUM=bit.InnerText;
this.labelCell.Text=NUM;
nOutNum=short.Parse(NUM, NumberStyles.AllowHexSpecifier);
NTPort.Outport(nAddress, (short)nOutNum);
Now, what I want to do is go though each node i.e. (one, two, three.... eight) one at a time, and on each one do the above code.
but make ....
bit=xmlDoc.SelectSingleNode("//Bytes/byte1");
unique to the specific node were on in the loop...
like if were on the one in bold...
<byte1>
<one>00</one>
<big><two>01</two></big>
<three>02</three>
<four>03</four>
<five>04</five>
<six>05</six>
<seven>06</seven>
<eight>07</eight>
</byte1>
then change it to...
bit=xmlDoc.SelectSingleNode("//Bytes/byte1/two");
so, it sounds reall confusing... I think all I need is a for loop or somthing... but the changing of the SelectSingleNode thing ruins me...
PLEASE HELP@!@!#@$K

do you know any free C# MD5 implementation (or I have to do it myself 
|
|
|
|

It is part of the .NET framework. Check for System.Security.Cryptography.MD5.

huh 
can't be... I hope it can be used for testing data integrity

Hi,
I've been trying to get the designer in visual studio to work for a class which isn't derived from "form".. It is a class derived directly from System..
I want the designer to work for my class so I can to drag the database connection from the "server explorer". And have it add all the code automatically to my class as is done for classes derived from "form"..
How can I do this??
Your help as always would be greatly appreciated!!

There was a quick "tip" about just this in one of the recent MSDNTV items. (Go to www.msdn.com/msdntv[^], then look at the archive for the one by Juval Lowy.)
Anyway, you temporarily inherit your class from Control (I think), which then enables the designer to do the database work for you. Then you remove the control inheritance if needed.

I'm doing something similar right now actually... Working on creating a GUI library and engine using DirectX that is designable.
You have to implement IComponent in your class (deriving from Component is a quick way to do this) because the DesignerHost (service provided and used by VS.NET) utilizes sites (ISite), which are the basis of components. Then you have to specify an IRootDesigner-implementing class in a DesignerAttribute for you IComponent class. You can try using ComponentDocumentDesigner for that if you don't need any custom designer stuff.
Also check out an article/sample named ShapeLibrary that gives a nice easy example of utilizing design-time services in .NET. You can find it here:
http://windowsforms.net/articles/shapedesigner.aspx[^]
Hope this helps...

Does anyone know how to locate a specific node in a treeview control? I have the full path (string) to the element, but now i want to select the given node in the treeview.
Is there any easy way to do this?
i.e i have the string "folderlevel1\folderlevel2\child1", and i want to select the node with name "child1" in the structure...
i'd really appreciate some help.

Use a foreach loop to loop through the Node's within the treeview.

Hello Gurus,
I inherited a MS Access database. One of the columns in a table happened to name with a SPACE in the middle, "FrameMaker Location". I know, it's not a smart way to name a column.
I was trying to insert some new records into the table. It only worked when I removed the SPACE from the column name (from my code and DB), like "FrameMakerLocation". Otherwise, I got an error like this "Syntax error in INSERT INTO statement".
Do you know any tricks so that I don't have to rename the column name???
Thanks so much in advance
Have a great Thur.
Khang Nguyen;)
Here is my draft of code (roughly)
===================================================================
DataRow row = dataSet.Tables[0].NewRow();
row["FrameMaker Location"] = sFrameMakerLoc;
dataSet.Tables[0].Rows.Add(row);
iNumOfAffectedRecs = adapter.Update(dataSet);

I am not sure but try enclosing the name in square brackets [ ].
