I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Regular Expressions Member 8054957-Jan-04 8:34 Member 805495 7-Jan-04 8:34  I am using the RegEx which needs to check for the value to be five digits before the decimal and 2 after the decimal or just five digits. and I am using System.Text.RegularExpressions.Regex exp = new System.Text.RegularExpressions.Regex("(^\\d{0,5}.{1}\\d{1,2}$)|(^\\d{1,5}$)"); With this it's only checking if the value is five digits before decimal and 2 after but not for just 5 digits. I entered 6 digits without decimal and it did not catch the exception. I don't know what's wrong. Any help ? Re: Regular Expressions Kentamanos7-Jan-04 9:27 Kentamanos 7-Jan-04 9:27  In most regular expression syntaxes, "." is a symbol that means "any character". You probably need to escape the . with a backslash, like "\.". I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Re: Regular Expressions Heath Stewart7-Jan-04 9:30 Heath Stewart 7-Jan-04 9:30  ^\d{5}(\.\d{2})?$ You didn't escape ".". Without escaping, this means that it matches any character or none. For instance, to match any 5 characters, you could use .{5}.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Re: Regular Expressions Kentamanos7-Jan-04 11:08 Kentamanos 7-Jan-04 11:08  I'm pretty sure you know this and just had a brain fart while typing, but for anyone else reading this... . actually means any character except possibly "\n" depending on options you set for your regular expressions. In other words, it doesn't match "none". More details here. I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Re: Regular Expressions Heath Stewart7-Jan-04 11:11 Heath Stewart 7-Jan-04 11:11  You're right - brain fart! I'm so used to typing .* for so many things I practically think of it as a single pattern element!

Re: Regular Expressions Member 8054957-Jan-04 9:58 Member 805495 7-Jan-04 9:58  I have changed my code and it works. Actually it supposed to be 1 to 5 digits, so I changed the first part to \d{1,5} How Windows works... profoundwhispers7-Jan-04 7:40 profoundwhispers 7-Jan-04 7:40  I need a book/document/article/website that could detail (regardless of the programming language, if required for examples) how the Windows operating system exactly works internally. Is there such a thing? I believe I cannot become a better programmer until I start understanding this: how the OS I'm coding for is actually behaving/responding to this code.

Mazdak7-Jan-04 7:49 Mazdak 7-Jan-04 7:49  I don't think you can find a book for a whole of windows cause it has very very different parts,also it is not open source ,so I'm not sure you can find out exactly all parts for that. But you can get some information if you want to work on a specific field ,you can get a book specially for that part. For example you can find out a lot about securities and how windows security acts in a books that specially about this topic. Same about other field.There is no general book for general purpose I think. Mazy No sig. available now.

Just reading a book on C windows programming will help. Writting even a few simple apps will give you a real good idea what is going on. DTrent Re: How Windows works... Heath Stewart7-Jan-04 9:20 Heath Stewart 7-Jan-04 9:20  How about the Microsoft Developer Network: http://msdn.microsoft.com[^]. Click on Library for the Platform SDK, Office SDK, .NET SDK, and many other topics. Learning the Platform SDK (PSDK) will give you some insights, but not many people can say how everything works internally. The PSDK seemed to be enough for the Wine development team to emulate Windows on linux and BSD!   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Kentamanos7-Jan-04 9:44 Kentamanos 7-Jan-04 9:44  You should take a look at the "Programming Windows" books (I think 5th edition is the current one?) by Charles Petzold. It won't explain how everything absolutely works inside Windows (only people like Matt Pietrek know that!), but it does show how to write Windows programs in straight C directly to API's. It doesn't use any sort of libraries that end up abstracting the job. I haven't looked at the newest edition, but the old ones used to sort of be a required reference. In any event, see if you can find a copy at a book store and peruse it. I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Re: How Windows works... profoundwhispers8-Jan-04 11:47 profoundwhispers 8-Jan-04 11:47  Kentamanos wrote: only people like Matt Pietrek know that!

He's written lots of articles for MS publications, a few books, and probably knows how Windows works more than 99.5% of MS employees (that's a guess, but it's probably not hyperbole).

I have a dataGrid that displays data from a DataSet. It seems to be working well. I have attached a context menu to it. What I am trying to do now is to read the selected row of this dataGrid. The farest I can go is getting the CurrentRowIndex of selected row. Is there a way to read something from the dataGrid at all? I can't find one method in that class that will do that for me. I am sorry if the question is stupid and there is a simple solution I passed by in the documentation. thanks a lot. Alexander.

Re: Read a row from dataGrid KevinMac7-Jan-04 5:33 KevinMac 7-Jan-04 5:33  I am not sure if this is what you are looking for but you can use the DataGrid.CurrentCell to get the row and column which you can use to read the dataset.
