Hi Willem,
In the designer script, I have the following events defined for the groupbox:
this.Conduit_Info_Group.MouseLeave += new System.EventHandler(this.Conduit_Info_Group_Exit);
this.Conduit_Info_Group.MouseEnter += new System.EventHandler(this.Conduit_Info_Group_Enter);
For the specific button, here is the defined event:
this.Conduit_AuthorisedAmount_Graph.Click += new System.EventHandler this.Conduit_AuthorisedAmount_Graph_Click);
Here are the above 3 methods:
private void Conduit_Info_Group_Enter(object sender, EventArgs e)
{
this.Conduit_AuthorisedAmount_Graph.Visible = true;
}
private void Conduit_Info_Group_Exit(object sender, EventArgs e)
{
this.Conduit_AuthorisedAmount_Graph.Visible = false;
}
private void Conduit_AuthorisedAmount_Graph_Click(object sender, EventArgs e)
{
<do stuff="">
}
I have also tried changing the enter and exit events as follows:
private void Conduit_Info_Group_Enter(object sender, EventArgs e)
{
this.Conduit_AuthorisedAmount_Graph.Visible = true;
this.Conduit_AuthorisedAmount_Graph.Click += new System.EventHandler(this.Conduit_AuthorisedAmount_Graph_Click);
}
private void Conduit_Info_Group_Exit(object sender, EventArgs e)
{
this.Conduit_AuthorisedAmount_Graph.Visible = false;
this.Conduit_AuthorisedAmount_Graph.Click -= new System.EventHandler(this.Conduit_AuthorisedAmount_Graph_Click);
}
In other words, I've reattached the event after showing the button and removed the event after hiding it, but it doesn't make a difference.
Another thing I've tried is removing the event MouseEnter once I've entered the groupbox and reattaching it after I leave. My thinking was that MouseEnter events were swamping the message queue and my button press event was getting lost, but still it wouldn't work!
Some days, VB6 just seems much simpler 
Many thanks,
John.

I wouldn't bother with detaching/reattaching; just attach it as usual and leave it.

If your just starting out then I'd recommend Visual C# 2005 Step-by-step (Microsoft Press)

The specification can be downloaded from Microsoft.

I would suggest Sams Teach Yourself: Visual Studio .NET 2003 in 21 days. (I am sure their are newer versions than 2003, but that is what I use). This book is the first book I turn to when I have a coding problem.

This is a project where we use webservice and windows service. windows service will send screenshot and information about the process and services of the client to server every ten second.
now i need to create a simulator which can generate more than 400(i.e 400 different computers requesting the server at the same instance of time) request at the same instance of time. HOW CAN IT BE ACHIEVED? what are the complication? how will the iis server handle it, and the ms-sql server handle it .....will there be network congestion...
somebody please share the idea.....
thanks in advance

There are free loadrunners on the internet that can help you generate the load you need.
However I can't tell what the server will do, this depends totally on how effecient the application is and how wel equipped the server is in terms of hardware.

A technique I've been playing with is to deploy the application as a "ClickOnce" app to a server share, but not make it available offline (so no start menu item is created on the users machine). Then I just send out a link to the .application file (file://server/share1/Support/Apps/MyWonderful.application). This works pretty well, and lets you specify what permissions you want your application to have.

I want to make the background of boolbutton images to be the same with system color.
How can I do? By the way, what does mean "ImageTransparentColor" property in VC#?
thanks.
|
|
|

ImageTransparentColor is the color within the image that will NOT be drawn. So, for example, to make a bitmap where the only thing visible is a single black dot, make one with a single black dot over a magenta background. Then set the ImageTransparentColor property to magenta, and it will not be drawn. This is used so the images don't have to fill in a rectangular area when drawn. I beleive this answers both questions. (to make it system color, simply set the ITC property as described above, then set the container's backcolor property to the system color). Hope this helps,
Sounds like somebody's got a case of the Mondays

Hi
How to restrict file type in one or more dynamic file upload controls in C# Web project.
For example I am creating code in code-behind
FileUpload uploadDataFile = new FileUpload();
In Browse dialog I want to restrict File Type as Xls, txt, CSv.
Please remember FileUpload controls are creating dynamically.
Thanks in Advance

It's not possible with FileUpload control. You can check the file extension and content type after submitting the form.

What would be the point? A particular extension doesn't guarantee what the contents are.

I have a tricky problem that I could really use some help on.
My app works with a number of very large float[] arrays that can easily use more memory than is available. To solve this I have created a memory manager that, in cases of dwindling memory, will dump some of the older arrays to temporary files. My app can request a reference to one of these arrays at any time, and the memory manager will recreate the array from the dumped copy if it's no longer in memory.
The problem is that my memory manager must not dump to disk any arrays that are currently being used by other parts of the app because a) any further changes to the array won't be reflected in the dumped copy, and b) dumping an array to disk that is being kept in memory by other parts of the application won't help memory load to begin with since the array won't be collected.
How can my memory manager, when it is deciding which arrays to dump to disk, check to see if other parts of the application are holding references to any of the arrays?
Thank you very much!

Why don't you use a cooperative approach, making your arrays released by their consumer to your memory manager?

exactly.
impelment same mechanism as COM object use.
add two methods:
AddReference()
ReleasReference()
and increase, decrease number of it's references in prive variable:
int referenceCount.
When AddReference() is called, referenceCount == 0 and array is dumped to file, recreate the array
When ReleasReference() is called and referenceCount == 1 , dump array to file.
Call AddReference() everytime you need to pass reference to another variable
Call ReleasReference() everytime you dispose this reference

Thank you for the throughtful replies.
An issue is that the app reached a quarter million lines of code and a fair level of complexity before it became clear that temporarily writing these arrays to disk would be necessary. Being able to figure out a way to do this that is transparent to the rest of the app would be a real lifesaver.

I know it is hard to hear but maybe a bit refactoring is worth. please, don't blame me for ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
