first use the code below to convert text to datetime

DateTime d=Convert.ToDateTime(lblFoo.Text);

then send d value to database.

With the limited information you have provided, a musefan search returned too many results to display. Please refine your query.

how 2 insert date and time both in one field??

do you want to insert 2 instances of the date and just 1 time or is it 2 instances of a date AND a time?

mjawadkhatri wrote:
data type of field is date

I didn't know fields had a 'date' type, I thought it was either 'Cow' or 'Sheep' or some other animal... oh, maybe your mean like a field in a table or something? It's hard to tell with such limited information

So, to sum up...

Are you referring to a field in a database? If so, what kind of database is it?
What format is the date and time data that you are trying to input? How is it stored?

P.S. the beauty of written messages is that people can re-read if they don't understand, so there is no need to shout if you fear they may not hear you the first time.

Just incase...

well if the column is of type data you can't place time along with it. I suggested backup your db or better first create some test data base create a column with type date, populate some entries and then change column type to date time and see results. I think changing column type form date to date time won't heart your existing changes because date time can accommodate more information so there would be no information loss in this way your change would be backward compatible.

Hi,

I have developed a smart client desktop application using SCSF.

It has an MDI and MDI child forms opens over it(It is similar to windows menu based application using MDI) .

The problem is that the MDI child forms (i.e. the views) take a few seconds to open and load.

Is there any way of minimising the time it takes.

The forms are having simple text boxes and labels and grids(which has two columns and is not populated during load)

I call a webservice at form load and have tried to comment the service call; Even then it takes the same time so I have ruled out the possibility of service delay.

Nothing else is done at the form load except the form is rendered

All MDI child forms(views) are taking the same time.

I dont have knowledge of SCSF internals, and how SCSF does all the handling of smart parts etc.
May be it might be tuned up to load the views faster or there is some way to make the CAB work faster which I am unaware of.

Could not find the forum related to SCSF so posting it here, please suggest in case you have knowledge of SCSF message board in code project.

Thanks in advance.

Sakshi

create Folder in remote Server with c#

23-Jul-09 2:48

First try with marking all your forms double buffered, secondly you may try to put some way to manage cache for example if you have downloaded something and its not changed then it would be better to make use of that instead of downloading same thing again and again. Secondly put some paging type thing in it to download specific parts for example instead of downloading 100 records from webservice on client side and then filtering them upon some criteria it would be better to ask webservice to return you only desired records. Secondly although I am not a fan of show/hide tech in windows forms but it may do the trick in your case and will be much faster then creating new form each time.

Dear All,
I am trying to create a folder in our remote server which is inside our domain.
i am using very simple code as CreateDirectory("dirPath").
i am getting an exception which says access denied to path "file path".
well i have user name and password which i can access remote server from windows.
how can i access remote server with my user id and Password and then create directory or files based on userid which i am logged in?

Access you domain control panel and assign read/write access to ASP.NET account. Folder creation requires ASP.NET code to run with write permission on desired location.

It is not ASP.Net application, its just Windows Application!!!
one way to use can be impersonation which i have done.
do we have some other ways?

How can I find a Bitmap within another Bitmap?

23-Jul-09 3:01

Then check how to configure the .NET Security and assign permissions. Sorry I was so busy in ASP.NET stuff that I didn't realized that you are asking for something with windows application Sigh | :sigh:

Hello.

I have two Bitmaps. I know that the small one is contained within the big one, and I want to search for it and return its position (a Rectangle):

public Rectangle findBitmap(Bitmap smallBmp, Bitmap bigBmp);

I can do this by making lots of pixel comparations in nested fors, but obviously it's too time-consuming since there can be literally hundreds of thousands of comparations. I need a *very* fast way to do this.

I've been reading for a while about Template Matching and I think it could be the way, but it's a difficult subject and I have not found any example or code that could help me. Could you please give me some advice?

Thanks in advance.

Check out CG's (Cristian Graus) article's.

He has a fair amount of article's on image processing.

Thank you, I will read them all, specially the Image Processing for Dummies series. Smile | :)

verence33323-Jul-09 2:26

23-Jul-09 2:26

OK, I've been reading those articles for a while. They are all very interesting and will use them in a future, but they focus on image filtering. There are nothing about finding a Bitmap in another Bitmap, which is what I need. :-/

So I still need help...

I guess you skimmed them and saw they where not about what you want/need.

Your best bet would be to wait for CG to pass by or to ask him.
He knows far more about this kind of stuff than I do.

verence33323-Jul-09 3:11

23-Jul-09 3:11

Yes, a while. Smile | :)

There's no need of in-depth reading how to transform an image when what I want is looking for a bitmap inside that image, and the algorithms are very similar in all the examples. Anyway, you're right and I must read them carefully when I have the time: maybe something could be done from the methods used to analyze the surrounding pixels of a given pixel.

I would like to ask CG, but someone already asked him about an algorithm to eliminate red eyes (something that I think would be similar to what I need, since it envolves looking for a pattern through an image) and CG answered that he never did it before.

I'm amazed that so few people has had this problem before. There are lots of possible applications that could be done with such an algorithm, I thought there would be plenty of solutions out there...

Don't know how long ago that was but it never hurts to ask. (well as long as you stay professional and polite it doesn't hurt Poke tongue | ;-P

)

Well I guess it's one of those things that not many people have to do. My job currently doesn't allow for stuff like this so...

Assuming your small bitmap is really *identical* to a section of your big bitmap (and not just something that *looks* the same) then basically you just want to perform a similar search to finding a substring within a string.

As you mentioned, you can brute force it with nested fors, or you can use a bit of smarts - you should be able to adapt an existing String searching algorithm[^] to search your pixel data instead

Help me! I'm turning into a grapefruit!
Buzzwords!

verence33323-Jul-09 20:34

23-Jul-09 20:34

Yes, the bitmap is really identical. What you say about adapting a String searching algorithm seems to be a good idea, thanks!

Hi verence,

I think what you need is a convolution integral.
I´m not sure (some years ago...) but I think it´s done by transforming both pictures to Fourier space and do a multiplication. In the result you search for the maximum and at that point is the center of your best match (you already know the size, should be the same as the small picture).

If you have no idea of higher mathematics this will be a hard job but I´m sorry I also don´t know more (e. g. code or good web sites that might help you). Try Google with the hints I gave you....

Bye
Thomas
