Re: Using Text Files OriginalGriff28-Aug-09 5:07 OriginalGriff 28-Aug-09 5:07  As Coding says, yes it is possible. How you do it will depend on what kind of info you have in your array, and what you want to do with the text file. If it is an array of strings, easy peasy. If it is an array of something else, then slightly harder - you will either have to do the work yourself or use a Formatter - XML, Binary or Soap.

Re: Using Text Files OriginalGriff28-Aug-09 5:34 OriginalGriff 28-Aug-09 5:34  Sorry, that was a little unhelpfull! For an array of strings, look at File.WriteAllLines[^]. To read it back, use ReadAllLines For an array of something else, you will need to: 1) Open file 2) Set up a loop through each element of the array 3) For each element, use ToString member, or string.Format to create a string 4) Write the string to the file 5) Close the file. To read them back, use the Parse method after reading the line. or look at BinaryFormatter, XMLFormatter and SoapFormatter in the MSDN, but these will not necessarily create a file you want to look at, or edit by hand!

That's why I apologised and gave more info. I'm trying to obey the new rules...but some of these questions do make it difficult.

DataBinding removal error kanchoette28-Aug-09 4:29 kanchoette 28-Aug-09 4:29  I have a textBox databound to a datatable via the properties window. It works well. I now need to remove this databinding. When doing this, via the properties window, and setting the Text section of DataBindings back to 'None' I get this error when re-running the solution: 'object reference not set to an instance of an object' for line: firstPaymentDateTextBox.DataBindings["Text"].Format += new ConvertEventHandler(DebtConvert.DateToString); it seems that VS 2008 does not remove this line when resetting the databinding via the designer properties window. It there a way around this please? As I have a lot of databindings to remove it seems a little tedious for such a, otherwise, powerful IDE. Re: DataBinding removal error Keith Barrow28-Aug-09 4:34 Keith Barrow 28-Aug-09 4:34  Why do you need to remove the bindings? Re: DataBinding removal error kanchoette30-Aug-09 4:21 kanchoette 30-Aug-09 4:21  The project has changed and the data binding for the textbox is no longer required.

Look here[^]. I suggest you first validate your image file by opening it succesfully with one of the reputed image processing programs, such as Adobe Photoshop.

Re: I need to resize a large image of more than 2MEGABYTE and I can not upload it to the program OriginalGriff28-Aug-09 5:10 OriginalGriff 28-Aug-09 5:10  I agree with Luc - I regularly work with images much bigger than 2Meg without problems in C#. I would suspect your code is at fault - try it with a small test image, and it will probably give the same error.

I want to resize the image from the file system and not from the image that appears on the screen. I have not harmed any tree to write this message but have produced a lot of smoke trying to resize the image.

Just for giggles, what are the dimensions of the image, in pixels, and the color depth?

Adobe editor products will open a file this large in win32; but very little else will. A while back I found a free GIS viewer that would load a monster image but can't recall what it was called. If it's only a one off your least painful option might be to use a liveCD to use the linux version of GIMP to resize it; as of a year ago the win32 version puked on a file that big. I haven't tested under win64, so I don't know if that combo would work any better. The latest nation. Procrastination.

You have to either find a library that will do what you want without loading the image, or write one yourself. Writing one yourself is NOT a trivial task, since you must known what the exact format of the image file is and how to work with the data. Then, you need to know about other image processing algorithms to pick out and blend individual pixels so that you can assemble the data in a smaller file, again, knowing the exact format of the image file you want write.

Re: I need to resize a large image of more than 2MEGABYTE and I can not upload it to the program OriginalGriff28-Aug-09 8:27 OriginalGriff 28-Aug-09 8:27  I think the problem may be your image then. I regularly deal with images that are in excess of 170Meg without problems, and as a simple test, I just saved one of these as a 8.5Meg .BMP file. In Paint (surely the most basic of basic rubbish image programs), it opens, edits, and saves without problems. I would try with a different image; I suspect yours is not what you think it is.

Re: I need to resize a large image of more than 2MEGABYTE and I can not upload it to the program DaveyM6928-Aug-09 13:24 DaveyM69 28-Aug-09 13:24  The only thing I can think of is to get a handle to the file without actually loading the file into memory (OpenFile [^] may do this - if not, there may be other functions that will). Once you have that, you can read the data in the file in sections and do what you wish with them, carefully disposing of each section from memory as you go. You'll need to understand the image format so you can interpret the headers and the image data itself. I have no idea with regards to the implementation of this - just an idea that may work. Dave BTW, in software, hope and pray is not a viable strategy. (Luc Pattyn) Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia) Why are you using VB6?

Reason: Not associated with a trusted SQL Server connection. Request This problem is generate when i connected with remote server i want to connection between two server to transfer data from one table to another.and i got data froms local server but when connect to another server then this problem arise.. From Mr.Saunat Sharma Re: Problem in connect with Remote server?? Searril28-Aug-09 3:57 Searril 28-Aug-09 3:57  Would probably be a good idea to start by pasting the code, especially your connection string. Also, have you checked the value of your User to ensure it's not null since that's showing up in your error message? Also again, if you're trying to use trusted connection (rather than SQL security) are you ensuring the workstation is actually logged into a domain account with proper rights? Re: Problem in connect with Remote server?? DoctorMick28-Aug-09 5:31 DoctorMick 28-Aug-09 5:31  Are you using web services to connect to the remote server? I seem to remember an issue with user details not being able to be passed through from one web service to another.
