This is a good question. I my self have trouble debugging my threaded application. I wrote a small logging routine that helped me solve my problems.
This is probably not the answer you were looking for, but I haven't found any other good solution to the problem. If you find one, I'd be glad to know.

No - you need to build or write a library for that.

Hello,
I have a raw data which has width of 1500 and height of 1000 resolution 300dpi, I want to convert this data in jpeg format.. how do I go about doing it?
Please help me with this asap.
Thank you.

Create a Bitmap object from the data (there is a constructor that takes a pointer to raw data), and save it to a file as a JPEG image.
Despite everything, the person most likely to be fooling you next is yourself.

X is a float and I need to perform x/10 and round the result up to the integer. So if result is 0.4 -> 1, if 1.1 -> 2, 2.7 -> 3. How can I do this in C#?

in order to prevent memory leaks can i force GC to collect memory which are having references.
|
|
|
|
|
yes, we can force GC by the following function.
GC.Collect()
|
|
|
|
|
ok, but this collects only the memory which are not having references , isn't it , what i want to know is , if there any method which i can use to get collected by GC when i give the name of the object even though it is having references

Why would you want to do that? What if the object gets GCed and then a method gets called on that object by one of the other references?
If you know the object is not going to be used further, call its Dispose() method, assuming it has one, or at least set the references to null so the GC can collect it.

why don't you just make your program crash the traditional ways instead of trying to invent a new one ?

No there isn't. There is something called WeakReference[^] which will allow the GC to collect even though there are references. MSDN has an example on it.

Hi All,
In a treeview control, if I select a node at level 5, I should shift the node with all its parent nodes to another treeview control.
For example,
node1
|--child1
|--child2
---|--child21
-------|--grandChild1
----------|--gradChild11
If I click on gradChild11, including its parents grandChild1, child21, child2, node1 should be shifted to other treeview in the same hierarchy.
Please guide to solve this problem.
Thanks in advance.

Hi all,
I've five tabs on a tab page and each contain list view. Views are populated with some data on a click event.
Once I click on a tab, it take bit of time to visible, at that time I can see the tab which is previously selected. So what I've done is refresh the tab when the tab selected index is change.
private void AllTabs_SelectedIndexChanged(object sender, EventArgs e)
{
AllTabs.SelectedTab.Refresh();
}
But still it's not work. Any comments?
I appreciate your help all the time...

Hi,

this is not clear.
Do you mean "I have 5 tab pages on a TabControl" ?
CodingLover wrote: I can see the tab which is previously selected

Do you mean "the previous tab remains visible for some time, only then the newly selected tag appears" ?
If so, your loading of the ListViews (or whatever gets loaded on SelectedIndexChanged() is too slow.
Refreshing all TabPages sure won't help, it is wasting CPU cycles on TabPages that are not visible!
Please clarify the situation, and use correct terms.

Sorry for the unclear description here.
Yes, I've 5 tab pages on a Tab Control.
Say I'm focusing on the first tab page. Once click on the second tab page, the first one is visible for a time and then suddenly appear the second one.
More important thing here is, this is happen only on the first time. When I click on any tabs after after this, works fine.
I appreciate your help all the time...

Hi,
not sure what you are showing on the tab pages, seems like the first access is slow.
Maybe you are listing filenames by scanning a disk, file caching would make that work faster the next time around.
Or you are accessing a database that hasn't been opened yet, so a first connection needs to be made,
and lots of code need to be jitted.
Whatever it is you need to do to load the pages, try doing it in the background *before* you select
a tab page, so the data (or at least the DB engine, file cache, whatever) gets warmed up.

Actually I read a text file and collect some data(read line by line to collect data) and added then in different list views in different tab pages. Actually each tab page have at least one list view.
I appreciate your help all the time...

Hi,
reading and parsing a text file should be a matter of milliseconds, not seconds, unless it is huge or a remote file on a slow network. XML is not particularly fast, and offers many ways to make it even slower.
I suggest you measure the time (with a StopWatch) it takes to obtain the data, to parse the data,
and to put it in the Control(s) assuming these are separate actions; with those numbers you can see which part is slow.
Alternatively measure the time it takes for the first data item, and for all N data items; if all is much faster than N times the first, you have heavy initial costs somewhere.
You could consider showing some relevant code, maybe someone will spot a problem at once...

Yes, I'm working on text files I can read up to 10MB file less than 10 seconds. I hope it's fine.
Each time I do this, clear all components, like list views and few text boxes. It's working fine extremely well. But unfortunate two things bugging on me.
First one is that tab select issue.
Seconds one is, as I said data adding start on a button click, and clear all components before adding again. In default first tab is selected and to populate all elements take less than 10 seconds.
Now say after first adding I select the second tab. And start adding data using the click event. This time it take around 20 seconds to adding data.
Can you make ma suggestion for me.
BTW: I've already use that SuspendLayout ResumeLayout in adding.
Thanks for the commenting here sir.
I appreciate your help all the time...
