• Change a select list display value upon selecting description

  - by eli

  Hello, I would like a select list that does the following: When the select list is open, display the list of descriptions. When the user selects an item, the select list will close an only the value will be displayed. The reason for this is to conserve space as the values will be much shorter. I'm hoping that there's an answer in jQuery. Thanks.

• K-nearest neighbour with closed-loop dimensions

  - by Tomas

  Hi, I've got a K-nearest neighbour problem where some of the dimensions are closed loops. For example one is 'time of day' and I'm matching for similarity so 'very early morning' is close to 'late evening', you can't just make it a linear scale from 'very early morning' at one end to 'late evening' at the other. How can I represent this in the data model? Is there an established way to handle this or a way to work around it?

• Third party components for both WPF and Silverlight

  - by rem

  I tried Xceed datagrid for WPF and liked it, but the problem is that this vendor doesn't have similar control for Silverlight.

Could you share your thoughts and experience on this? What whould you recommend?

• Cannot work for 2nd iteration because of writing delay.

  - by karikari

  My code's IF-THEN does not work for 2nd iteration. This is due to, the jar processing take some time to write it result inside the output.txt. Since the writing is a bit late, my code's 2nd iteration will always read the previous written value inside the output.txt in order to pass it to the IF-THEN. For example, in 1st iteration: output.txt -- 0.9888 twrite.txt -- msg: ok 2nd iteration: output.txt -- 0.5555 twrite.txt -- msg: ok //the IF-THEN still gives this result which is based on previous iteration. it should be msg: not ok . since it is < 0.7 I need help, how to solve this 'delay' problem? HRESULT CButtonDemoBHO::onDocumentComplete(IDispatch *pDisp, VARIANT *vUrl){ ATLTRACE("CButtonDemoBHO::onDocumentComplete %S\n", vUrl->bstrVal); WinHttpClient client(vUrl->bstrVal); client.SendHttpRequest(); wstring httpResponseHeader = client.GetHttpResponseHeader(); wstring httpResponse = client.GetHttpResponse(); writeToLog(httpResponse.c_str()); if (isMainFrame(pDisp)){ m_normalPageLoad=false; FILE *child = _popen("javaw -jar c:\\simmetrics.jar c:\\chtml.txt c:\\thtml.txt > c:\\output.txt", "r"); fclose(child); char readnumber[10]; float f = 0; FILE *file11 = fopen("c:\\output.txt","r"); char* p = fgets(readnumber,10,file11); std::istringstream iss(p); iss >> f; if (f > 0.7) { wfstream file12 ("c:\\twrite.txt", ios_base::out); file12 << "Msg: ok"; file12.close(); } else { wfstream file12 ("c:\\twrite.txt", ios_base::out); file12 << "Msg: not ok"; file12.close(); } iss.clear(); fclose(file11); return S_OK; } return S_OK; }

• python: html writer?

  - by Bin Chen

  With jquery it's very easy to insert some element inside another element using the selector technology, I am wondering if there is any python library that can do things similar with jquery, the reason is I want server side python program to produce the static pages, which needs to parse the html and insert something into it. Or other alternative, not in python language at all? EDIT: To be clear, I want to use python to write below program: h = html.parse('temp.html') h.find('#idnum').html('<b>my html generated</b>') h.close()

• finding and returning a string with a specified prefix

  - by tipu

  I am close but I am not sure what to do with the restuling match object. If I do p = re.search('[/@.* /]', str) I'll get any words that start with @ and end up with a space. This is what I want. However this returns a Match object that I dont' know what to do with. What's the most computationally efficient way of finding and returning a string which is prefixed with a @? For example, "Hi there @guy" After doing the proper calculations, I would be returned guy

• Write file at a specific value and line

  - by user2828891

  I want to write data at a specified value in a text file from a text box. Here is a example: item_begin etcitem 3344 item_type=etcitem is first line and item_begin weapon 3343 item_type=weapon is second. Well i want to replace item_type=weapon at second line with item_type=armor. Here is code so far: var data2 = File.WriteAllLines("itemdata.txt") .Where(x => x.Contains("3343")) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); But returns error at WriteAllLines. Here is the readline part code: var data = File.ReadLines("itemdata.txt") .Where(x => x.Contains("3343")) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); //call values textitem_type.Text = data["item_type"]; And want to write the same value I change on textitem_type.Text after read. I used this to reaplace but replaces all values with same name from line and returns me in text only 1 line. Code: private void button2_Click(object sender, EventArgs e) { var data = File .ReadLines("itemdata.txt") .Where(x => x.Contains(itemSrchtxt.Text)) .Take(1) .SelectMany(x => x.Split('\t')) .Select(x => x.Split('=')) .Where(x => x.Length > 1) .ToDictionary(x => x[0].Trim(), x => x[1]); StreamReader reader = new StreamReader(Directory.GetCurrentDirectory() + @"\itemdata.txt"); string content = reader.ReadLine(); reader.Close(); content = Regex.Replace(content, data["item_type"], textitem_type.Text); StreamWriter write = new StreamWriter(Directory.GetCurrentDirectory() + @"\itemdata.txt"); write.WriteLine(content); write.Close(); }

• A question about making a C# class persistent during a file load

  - by Adam

  Apologies for the indescriptive title, however it's the best I could think of for the moment. Basically, I've written a singleton class that loads files into a database. These files are typically large, and take hours to process. What I am looking for is to make a method where I can have this class running, and be able to call methods from within it, even if it's calling class is shut down. The singleton class is simple. It starts a thread that loads the file into the database, while having methods to report on the current status. In a nutshell it's al little like this: public sealed class BulkFileLoader { static BulkFileLoader instance = null; int currentCount = 0; BulkFileLoader() public static BulkFileLoader Instance { // Instanciate the instance class if necessary, and return it } public void Go() { // kick of 'ProcessFile' thread } public void GetCurrentCount() { return currentCount; } private void ProcessFile() { while (more rows in the import file) { // insert the row into the database currentCount++; } } } The idea is that you can get an instance of BulkFileLoader to execute, which will process a file to load, while at any time you can get realtime updates on the number of rows its done so far using the GetCurrentCount() method. This works fine, except the calling class needs to stay open the whole time for the processing to continue. As soon as I stop the calling class, the BulkFileLoader instance is removed, and it stops processing the file. What I am after is a solution where it will continue to run independently, regardless of what happens to the calling class. I then tried another approach. I created a simple console application that kicks off the BulkFileLoader, and then wrapped it around as a process. This fixes one problem, since now when I kick off the process, the file will continue to load even if I close the class that called the process. However, now the problem I have is that cannot get updates on the current count, since if I try and get the instance of BulkFileLoader (which, as mentioned before is a singleton), it creates a new instance, rather than returning the instance that is currently in the executing process. It would appear that singletons don't extend into the scope of other processes running on the machine. In the end, I want to be able to kick off the BulkFileLoader, and at any time be able to find out how many rows it's processed. However, that is even if I close the application I used to start it. Can anyone see a solution to my problem?

• Word 2007 macros: is there an OnPrint event I can attach a macro to?

  - by notnot

  I'm looking to do a formatting check on word files before they get sent to the printer and it needs to be completely transparent to the user (no extra controls, just using the standard print options available through the UI). Is there an OnPrint or BeforePrint event, or something that can be used in that respect which I could attach a macro to, the same way I can with Open, Close, or Save? This feels like it should be simple... but those are famous last words. Thanks in advance, Rob
