  • .net Generic Calls <T>

    - by Ryan
    I have a function that accepts a generic parameter T that is of type class like so : public Func<T, bool> MyMethod<T>(string paramName, object value) where T : class But when calling the function I do not have direct access to the class that needs to be the parameter. MyMethod<foo>("foo1", "foo2") Is there a way I can get the class foo via other means like reflection so I can use the function?

  • Idiomatic scheme and generic programming, why only on numbers ?

    - by Skeptic
    Hi, In Scheme, procedures like +, -, *, / works on different types of numbers, but we don't much see any other generic procedures. For example, length works only on list so that vector-length and string-length are needed. I guess it comes from the fact that the language doesn't really offer any mechanism for defining generic procedure (except cond of course) like "type classes" in Haskell or a standardized object system. Is there an idiomatic scheme way to handle generic procedures that I'm not aware of ?

  • My winform application doesn't work on others' pc without vs 2010 installed

    - by wings
    Just like I said, my winform application works properly on computers with VS installed, but on other computers, it will crash due to a FileNotFound Exception. I used using Application = Microsoft.Office.Interop.Excel.Application; in my source code to generate a Excel file, and the problem occurs as soon as the Excel-related function is called. But I don't know what it refers to exactly. Do I have to get some .dll included along with the .exe file? And what DLL is that? Below are part of my codes: private void FileExport(object objTable) { StartWaiting(); string[,] table = null; try { table = (string[,])objTable; } catch (Exception ex) { ShowStatus(ex.Message, StatusType.Warning); } if (table == null) { return; } Application excelApp = new Application { DisplayAlerts = false }; Workbooks workbooks = excelApp.Workbooks; Workbook workbook = workbooks.Add(XlWBATemplate.xlWBATWorksheet); Worksheet worksheet = (Worksheet)workbook.Worksheets[1]; worksheet.Name = "TABLE"; for (int i = 0; i < table.GetLength(0); i++) { for (int j = 0; j < table.GetLength(1); j++) { worksheet.Cells[i + 1, j + 1] = table[i, j]; } } Range range = excelApp.Range["A1", "H1"]; range.Merge(); range.Font.Bold = true; range.Font.Size = 15; range.RowHeight = 50; range.EntireRow.AutoFit(); range = excelApp.Range["A2", "H8"]; range.Font.Size = 11; range = excelApp.Range["A1", "H8"]; range.NumberFormatLocal = "@"; range.RowHeight = 300; range.ColumnWidth = 50; range.HorizontalAlignment = XlHAlign.xlHAlignCenter; range.VerticalAlignment = XlVAlign.xlVAlignCenter; range.EntireRow.AutoFit(); range.EntireColumn.AutoFit(); worksheet.UsedRange.Borders.LineStyle = 1; Invoke(new MainThreadInvokerDelegate(SaveAs), new object[] { worksheet, workbook, excelApp } ); EndWaiting(); }

  • GAE update different fields of the same entity

    - by bach
    Hi, UserA and UserB are changing objectA.filedA objectA.filedB respectively and at the same time. Because they are not changing the same field one might think that there are no overlaps. Is that true? or the implementation of pm.makePersistnace() actually override the whole object... good to know...

  • Difference between abstract class and interface

    - by nectar
    A class implementing an interface has to implement all the methods of the interface, but if that class is implementing an abctract class is it necessary to implement all abstract methods? If not, can we create the object of that class which is implementing the Abstract class???

  • Hibernate Lazy Loading Proxy Incompatable w/ Other Frameworks

    - by bowsie
    I've come across several instances where frameworks that take POJOs to do some work crap-out with proxied hibernate beans. For example if I xml annotate a bean for framework X and pass it to framework X it doesn't recognise the bean because it is passed the proxied object - which has no annotations for framework X. Is there a common solution to this? I'd prefer not to define the bean as eager loaded, or turn of lazy-loading anywhere in the application. Thoughts? Thanks.

  • Custom cell in list in Flash AS3

    - by Stian Flatby
    I am no expert in Flash, and I need some quick help here, without needing to learn everything from scratch. Short story, I have to make a list where each cell contains an image, two labels, and a button. List/Cell example: img - label - label - button img - label - label - button As a Java-programmer, I have tried to quicly learn the syntax and visualness of Flash and AS3, but with no luck so far. I have fairly understood the basics of movie clips etc. I saw a tutorial on how to add a list, and add some text to it. So I dragged in a list, and in the code went list.addItem({label:"hello"}); , and that worked ofc. So i thought if I double-clicked the MC of the list, i would get to tweak some things. In there I have been wandering around different halls of cell-renderers etc. I have now come to the point that I entered the CellRenderer_skinUp or something, and customized it to my liking. When this was done, I expected i could use list.addItem(); and get an empty "version" of my cell, with the img, labels and the button. But AS3 expects an input in addItem. From my object-oriented view, I am thinking that i have to create an object of the cell i have made, but i have no luck reaching it.. I tried to go var test:CellRenderer = list.listItem; list.addItem(test); ..But with no luck. This is just for funsies, but I really want to make this work, however not so much that I am willing to read up on ALOT of Flash and AS3. I felt that I was closing in on the prize, but the compiler expected a semicolon after the variable (list.addItem({test:something});). Note: If possible, I do NOT want this: list.addItem({image:"src",label:"text",label"text",button:"text"}); Well.. It actually is what I want, but I would really like to custom-draw everything. Does anyone get what I am trying to do, and has any answers for me? Am I approaching this the wrong way? I have searched the interwebs for custom list-cells, but with no luck. Please, any guiding here is appreciated! Sti

  • boost::asio and socket ownership

    - by vedro so snegom
    Hello I've two classes (Negotiator, Client), both has their own boost::asio::ip::tcp::socket. Is there a way to transfer socket object to Client after negotiation is finished. I'm looking forward to do something like that: boost::asio::ip::tcp::socket sock1(io); //... boost::asio::ip::tcp::socket sock2; sock2.assign(sock1); This operation must guarantee that the connection won't be closed when sock1 is destroyed.

  • What happens if an exception is thrown in finalize()

    - by Psykocyber
    What would happen if an exception is thrown during the execution of finalize()? Is the stack unwind like normally? Does it continue finalize() and ignore the exception? Does it stop finalize() and continue GC the object? Or something else? I'm not looking for guidelines of using finalize() there are plently of pages explaining that.
