ToolTip is the general method of adding help to a control, I have been known to add a help icon to each form and allow the user to edit their own help data, never happens of course!

Hi Michael,

It might be helpful to know if you are speaking "in general" here, or if you have a specific scenario in mind.

Is it the case that you want what is shown to provide information to persist until the user "tells it to go away," or is a ToolTip, which you do have some control over how long it stays visible, good enough.

Do you have a certain type of user in mind here: a programmer, for example; or, a very non-technical end-user ? I'm guessing you intend this for a programmer.

It seems almost 100% certain to me you are talking about displaying information while your application is running, but, if that's not the case, please do state that.

yours, Bill

Reading a good programming book should help you get started.

I agree with Abhinav S. Get a starters book somewhere and read it from A-Z. Don't start out too specific (like WPF or WCF), but rather a "Learning .Net with C#" kind of book.

good luck taking the first steps.

Their are many standard publications who have good books but you should always buy books with label like beginner guide or absolute beginner guide or guide for dummies(no offense) and yes you must start with core c#, it hurts me too much when some random guy show up for interview and fail to explain Object callings and references.

So, what you have in mind is that there is no text currently selected, but the Textbox has focus, and the insertion point is set somewhere, and you press a button, or something, and then the next characters you type are in bold, italic, etc., depending on what buttons you pressed ?

What have you tried so far ? What are you doing now, in code, that sets the selected text to bold, italic, etc. ?

Then, remember Word when press "I" for the Italic the cursor change and the text to. In my case i need input text and after select all text e press "I" for changes. But i want to work as the Word.

Now i use ApplyPropertyValue();

.Net , Help is Designing SSIS component Package 2012 in c#

9-Aug-13 2:40

I want to design SSIS component when i load the package.
My goal is to reproduce the components contained in a package when I load it.
The package is loaded by c# , winform application , i can load package ( doc.LoadXml(packageXml))

When the xml is loaded, I retrieve the layout of the package and its components. . With the layout, I can get the coordinates of the component and redraw one by one.

well that's what I think.

This link
http://pragmaticworks.com/Products/BI-xPress/Features/SSISMonitoringConsole.aspx ,
picture 3 and 4 show what I would like to have as result.
This example concerns the 2012 packages

Also the picture 3 of the following link shows the result of thepackages in 2008 and 2005

Thx for any Help.

How to put 2 copies of same dataset on a form

I need to put 2 copies of the same dataset on a form. Then I can bind my 2 grids to one copy each and I can then supply different parameters to each dataset on the fill. I can't figure out how to get the second copy of the dataset onto the form... can someone advise please?

Thanks.

I think datasets have a method that's called copy and clone. see here[^] it effectively takes a deep copy of the object.

hope this helps.

To ask a proper question. It is far from clear what your problem is, and it is unlikely that anyone is going to provide the code for you.

Converting Byte array into integer?

Kiran Satish8-Aug-13 9:11

Kiran Satish

8-Aug-13 9:11

Hello all,

Looks like this is a basic question that I somehow is not able to figure it out properly. The method I am using works for Hex numbers that does not contain 0 in its lower byte.

I guess I have to use a different approach to get around this problem, which I am not able to quite figure it out.

I am reading values off of an IC which pushes out serial data in bits and the total length of the output is always 16bits which are read into two bytes. So, when the value is 255 its fine when I convert it into integer. But when the output from the chip is equivalent to 256, it turns out to be '1' in Upper byte and '0' in lower byte which is not being converted to 256 but rather to 16 using the following code.

string hexValue = In[0].ToString("X") + In[1].ToString("X");
int hscandacvalue = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);

Any suggestions?

thanks

The problem with this is that it turns eg 0x01 (as a byte) into the string 1, and then the leading zero is lost. That's a problem, because you're concatenating in front of it. You could fix that by using X2, but don't.

But you don't need any of this weird string business anyway, you can simply use math (lowbyte + 256 * highbyte)

hi folks,
i want a general idea of how to create a server-client environment in window application(c#.net). So what i am looking for is:
1. A sample mini project so far none found on google Mad | :mad:

2. what technology should i use udp/tcp/socket layer or something else.
3. how does client A gets notification of SQL update by client B ;when both are viewing/working on same table. So the record can get an auto refresh or something like that.

Regards

Don't make this too hard. I wrote one a few years ago and started like you are. I wanted PC-A to tell everyone else that it had just made a change.

But the easy was is for each pc to monitor the db and find the changes on it's own. You don't need any network code to handle that. For me it could be a few minutes behind so it worked great.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
