How will u load dynamic assembly? How will create assemblies at run time?

You can use reflection to load the assembly dynamically.

I downloaded the gdWrapper, and wrote some code to draw a part on the fly. I want to save the png file as a file, and I want to stuff the PngStream into a SQL Server Image Table Column.
The instructions for the gdwrapper are kind of vague, can't figure out what the call is for writing the file to the disk drive.
Here is what I have so far , This is my first time using JScript
I call the file 'RenderPart.asp'
<%@language=jscript%>
<%
//Gather all the data needed to make the drawing
//var TX = Request.QueryString("TX") * 3
//var TY = Request.QueryString("TY") * 3
//var AX = Request.QueryString("AX") * 3
//var AY = Request.QueryString("AY") * 3
//var BX = Request.QueryString("BX") * 3
//var BY = Request.QueryString("BY") * 3
//var BV = Request.QueryString("BV") * 3
//var CX = Request.QueryString("CX") * 3
//var CY = Request.QueryString("CY") * 3
//var JobNumber = Request.QueryString("JN")
var TX = 120
var TY = 90
var AX = 18
var AY = 44.7868
var BX = 39.2132
var BY = 45.2132
var BV = 30
var CX = 80.7868
var CY = 24
var JobNumber = "CF1"
// Write image/png header
Response.ContentType = "image/png";
// Set 'dynamic' content to expire immediately (depends on situation)
Response.Expires = -1000;
// Create variables
var gdImage = Server.CreateObject("GDLibrary.gdImage");
// Create a new paleted image in memory ... or ...
//gdImage.Create(250, 200);
//Calculate the image size if it gets real big
var CTX;
var CTY;
if(TX > 480) {
CTX = TX + 50;
} else {
CTX = 480;
}
if(TY > 320 ) {
CTY = TY + 40;
} else {
CTY = 320;
}
gdImage.Create(CTX, CTY);
// Add/Return RGB True Color values
var White = gdImage.ColorAllocate(255, 255, 255);
var Black = gdImage.ColorAllocate(0, 0, 0);
var Red = gdImage.ColorAllocate(255, 0, 0);
var Blue = gdImage.ColorAllocate(0, 0, 255);
var Green = gdImage.ColorAllocate(0, 255, 0);
//Calculate TotalBox First, Then Draw it
//gdImage.Rectangle(0, 0, TX, TY, Black);
//Caluclate PartB, then Draw it
//(sX, sY, fX, fY, color)
gdImage.Line(0, 0, 0, BY, Red); //Verrical

gdImage.Line(0, BY, AX, BY, Red);
gdImage.Line(BX, 0, BX, CY, Red);
gdImage.Line(AX, BY, BX, CY, Red); //Vortex
//Calculate PartA Next, then draw it
//(sX, sY, fX, fY, color)
gdImage.Rectangle(0, BY, AX, AY+BY, Red);
//Calculate PartC, then Draw it
//(sX, sY, fX, fY, color)
gdImage.Rectangle(BX, 0, CX+BX, CY, Red);
// Label the Drawing now
//gdImage.Chars(gdImage.FontGetMediumBold(), 75, 10, "Horizontal Y-Axis", Black);
//gdImage.CharsUp(gdImage.FontGetMediumBold(), 460, 225, "Vertical X-Axis", Black);
//gdImage.Chars(gdImage.FontGetTiny(), AX / 4, (BY / 4), "Part B", Black);
//gdImage.Chars(gdImage.FontGetTiny(), AX / 4, AY, "Part A", Black);
//gdImage.Chars(gdImage.FontGetTiny(), (CX / 3) + BX, (BY / 4), "Part C", Black);

gdImage.Chars(gdImage.FontGetSmall(), 10, TY + 35, "Job Number: " + JobNumber, Black);
// Before output, if we want a Palleted Png (256 color), run the next command!
gdImage.TrueColorToPalette(false, 256);
// For Gradients, Dithering will help but increase the file size!
// Return a Png data stream

I was wondering if there is a way to merge tables together in a dataset.
I can pull a "Select * FROM Table A" and fill the DataSet then do it for Table B as well in no time flat. But I don't know how to merge them into one table
But if I do a "Select a.Name, a.ID, b.ID, b.Number FROM a.Table AND b.Table B WHERE a.ID=b.ID" and fill a single table in my dataSet, but it takes so much longer because I am doing this over a connection.
Or am I missing the boat and something other than a DataSet is the way to go?
Thanks!

You can do selects and joins on DataSets, but it's more complicated and annoying than doing it on the database.
I don't understand why a simple inner join takes noticably longer than a flat query. It certainly has nothing to do with your connection to the database. More likely, you've got a poorly-optimized database. Your previous question was about MySQL, so I'll assume that's what you're using. MySQL should be able to do a 1-column inner join on a million rows with a proper index in less time than a table scan (which is what you'd get if you did select name, id) from each table. I don't respect MySQL very much, but it's a hell of a lot more competent than to whimper on a 1-column inner join.
What's your DB look like?

The dataset is capable of joining tables, but the database is generally better at it.
If you join the tables in the query it should take about the same time to fetch as fetching the tables separately, unless one of the tables are much larger than the other so that joining the tables creates a result with mostly duplicates from the smaller table.

I have multiple tables that I'm pullng into a DataSet.
My first method was to run a query and merge the data I need into one table using the MySQL command.
But here's my problem. I have a shared field x_ID where in one Table A it is null and in Table B it is the primary.
For example:
I have
Table A
Customer_Purchase $5, $4, $3
Customer_ID 1, 2, null
Table B
Customer_ID 1, 2, 3, etc
Customer_Name ...
My return for Who purchased what would only have 2 rows and I'd rather have all three, even though one would have no name in it.
Thanks!

1. You're posting on the wrong board. This is a SQL question.
2. What's your SQL query?
3. Tell us a little more about your table structure.
Otherwise:
If Customer_ID in Table A is a foreign key, you shouldn't allow nulls. If you have to, and you want three rows back, do an outer join. You still won't get a Customer_Name for the null/$3 record because there's no null key in Table B, which was probably enforced because Customer_ID is probably a primary key.
If you post your SQL query, I can probably help you more specifically.

Dear gurus,
my app has a rich user-interface which I have to test extensively by mouse-clicking on all the menus, buttons,.....
My idea now is to create a small tool which sends all this clicks,... automatically to my application for testing the user-interface.
Does anyone have an idea how this can be accomplished?
Or are there any other ideas.
Kind regards

Use the System.Windows.Forms.Cursor class, this has a property Position, you can use this to move the cursor.
Regarding actually pushing the mouse button I'm not sure if you can do this without having to resort to calling the Windows API, from what I remember the mouse events are quite easy to send using the appropriate API.
This[^] article may be useful to you.

This doesn't seem like the best way to accomplish this task. There are many, many applications out there that can be used to script mouse moves and clicks. You'll save yourself a lot of time and trouble if you use one of those.

While implementing an automated GUI test tool may be an interesting and fun challenge, you may be better off purchasing au automated test tool. There are quite a few on the market, and you should be able to get one for as little as $500. In the long run, it would be cheaper to purchase the tool than to invest your time into developing your own. Just my two cents...

You can get one for significantly less than $500: free. There are shareware and freeware click generators out there that work much better than anything anyone on this board can write in a couple day's time (no offense to anyone intended).

Hallo !
Thanks for your answer.
Can you give me any hint which tools are free-/shareware?
With kind regard

Hi,
I have a VB application using a .Net(C#) dll.I made the application wait for particular time from the .net dll and during the wait if i move between other open windows,the VB application gets hanged or becomes blank screened.
I tried using System.Windows.Forms.Application.DoEvents() to repaint the Vb application but it is not that effective.
I am totally clueless

What exactly are you trying to do? Are you trying to modify the VB application? If so, you may get better results in the VB group. Likewise, if you're trying to modify the C# DLL, you may get better results in the C# group.
When you say that you "made the application wait for a particular time," how did you do this? Chances are, you did this incorrectly, and this is causing your blank screen. If you block the UI thread while you're waiting, the screen won't paint.

Why do you ask the same question again? Keep it in one thread.

The runtime doesn't trust the location you're running it from, because your developing it on your machine VS has probably set all the required permissions. To run it from another PC you need to goto: Control Panel -> Administrative Tools -> Microsoft .NET [version (e.g. 2.0)] Configuration. Inside the configuration pane select "Runtime Security Policy" -> Increase Assembly Trust, a wizard will popup and guide you through the steps required to allow that program to run from the network (note this can be configured on an app by app basis or for the entire machine).

If i use unmanaged code in my application then how does runtime comes to know that this particular piece of code is unmanaged code.

If you're using unmanaged (unsafe) code directly in your application, you need to mark it unsafe or it won't compile. The runtime will know because you marked it. Google "unsafe code tutorial" for more help.
If you're using an unmanaged assembly (e.g. -- COM), the wrapper will deal with the unmanaged code, but you need to make sure you clean up any resources in your disposal method. Any proper tutorial on how to correctly implement the Dispose method in your classes should tell you where to put the code for disposing of unmanaged resources.
