  • Jasper Reports: How can i have multiple growing subreports in a report?

    - by Sandeep Jindal
    Hi, My Requirement is to show two sub reports in a Report. What I am doing is, I have created two sub-reports and put that into a report. But the issue is that, both the sub reports are growing (i.e. their height is not static as the number of records are variable). I just want the second sub=report to appear after the end of first sub-report. How can I achieve the same? Regards, Sandeep Jindal

  • Validate subset of a form using jQuery Validate plugin

    - by Andrew Davey
    My HTML form has a number of divs that are the steps of a wizard. Upon clicking a "next" button I want to validate just the active div. I'm using the jQuery.Validate.js plugin. Each div has an ID, so I want a way to say something like: wizardForm.validate().element('#first-step :input') but this only validates the first input, not all of them. How can I validate all inputs within a div?

  • Which platform can we expect one's complement being used there?

    - by Jian Lin
    For some questions such as checking whether a number is odd or even, I noted the comment, a & 1 won't work when it is a one's complement machine or when the code is ported to a platform that uses one's complement. Since 30 years ago on the Superboard, TRS-80, Apple II, I haven't seen a system with one's complement. Are there popular systems that use one's complement still, or do we have some cell phone or mobile device that uses one's complement?

  • Using Microsoft.Office.Interop to save created file with C#

    - by Eyla
    I have the this code that will create excel file and work sheet then insert same values. The problem I'm facing that I'm not able to save the file with name giving ten colse it. I used SaveAs but did not work: wb.SaveAs(@"C:\mymytest.xlsx", missing, missing, missing, missing, missing, XlSaveAsAccessMode.xlExclusive, missing, missing, missing, missing, missing); this line of code would give me this error: Microsoft Office Excel cannot access the file 'C:\A3195000'. There are several possible reasons: • The file name or path does not exist. • The file is being used by another program. • The workbook you are trying to save has the same name as a currently open workbook. please advice to solve this problem. here is my code: private void button1_Click(object sender, EventArgs e) { Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); if (xlApp == null) { MessageBox.Show("EXCEL could not be started. Check that your office installation and project references are correct."); return; } xlApp.Visible = true; Workbook wb = xlApp.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Worksheet ws = (Worksheet)wb.Worksheets[1]; if (ws == null) { MessageBox.Show("Worksheet could not be created. Check that your office installation and project references are correct."); } // Select the Excel cells, in the range c1 to c7 in the worksheet. Range aRange = ws.get_Range("C1", "C7"); if (aRange == null) { MessageBox.Show("Could not get a range. Check to be sure you have the correct versions of the office DLLs."); } // Fill the cells in the C1 to C7 range of the worksheet with the number 6. Object[] args = new Object[1]; args[0] = 6; aRange.GetType().InvokeMember("Value", BindingFlags.SetProperty, null, aRange, args); // Change the cells in the C1 to C7 range of the worksheet to the number 8. aRange.Value2 = 8; // object missing = Type.Missing; // wb.SaveAs(@"C:\mymytest.xlsx", missing, missing, missing, missing, //missing, XlSaveAsAccessMode.xlExclusive, missing, missing, missing, missing, //missing); }

  • Float PPM image file format?

    - by Luca
    I've found a PPM image with the header starting with PF. The resolution number is stored in floating point (-1.000). No comments are inserted to get how it was produced. From the resolution, each pixel is composed by 12 bytes (4 bytes per component)... I suppose they are float or integer numbers. The problem is that I cannot get a clear image. Someone has already found this kind of images?

  • Does Objective-C support Mixin like Ruby?

    - by hacksignal
    In Ruby, there's Modules and you can extend a class by "mixing-in" the module. Module myModule def printone print "one" end end Class myClass extend myModule end theOne = myClass.new theOne.printone >> one In Objective-C, I find that I have a set of common methods that I want a number of Class to "inherit". What other ways can I achieve this without creating a common class and deriving all from that common class?

  • mysql query is producing more results than it should

    - by user253530
    SELECT S.CLIENT,S.IP_DOMAIN as IP, IFNULL(K.DATE, DATE '0000-00-00') AS RecentDate FROM PLD_SERVERS AS S JOIN PLD_SEARCHES AS K ON S.ID = K.SERVER_ID This query will produce as many results as entries in the PLD_SEARCHES. For example: I have 3 entries in PLD_SERVERS and 18 entries in PLD_SEARCHES. The output of this query will be 18 but i need it to be 3 (as the number of PLD_SERVERS entries) with the recent date as a join field from PLD_SEARCHES.

  • ModelMultipleChoiceField and reverse()

    I have a form containing a ModelMultipleChoiceField. Is it possible to come up with a url mapping that will capture a varying number of parameters from said ModelMultipleChoiceField? I find myself doing a reverse() call in the view passing the arguments of the form submission and realized that I don't know how to represent, in the urlconf, the multiple values from the SELECT tag rendered for the ModelMultipleChoiceField...

  • iPhone UIControl and Subview

    - by Jack Thompson
    I currently have a UIControl, which has a number of subviews (image, label). Unfortunately when I use addTarget etc. It doesn't detect touches on the subviews. [myCustomView addTarget:self action:@selector(touchedView:) forControlEvents:UIControlEventTouchUpInside]; Is it possible for the UIControl to detect touches on subviews or should i be approaching it differently.

  • Form contents not showing in email

    - by fmz
    This is a followup to a question I posted yesterday. I thought everything was working fine, but today, I am not getting any results in the email from the drop down field. Here is the form code in question: <label for="purpose"><span class="required">*</span> Purpose</label> <select id="purpose" name="purpose" style="width: 300px; height:35px;"> <option value="" selected="selected">-- Select One --</option> <option value="I am interested in your services">I am interested in your services!</option> <option value="I am interested in a partnership">I am interested in a partnership!</option> <option value="I am interested in a job">I am interested in a job!</option> </select> It is then processed in PHP and should output the selected option to an email, however the Reason for Contact line always comes through with nothing in it. Here is the PHP code: <?php if(!$_POST) exit; $name = $_POST['name']; $company = $_POST['company']; $email = $_POST['email']; $phone = $_POST['phone']; $purpose = $_POST['purpose']; $comments = $_POST['comments']; $verify = $_POST['verify']; if(trim($name) == '') { echo '<div class="error_message">Attention!

  • DynamicMethod for ConstructorInfo.Invoke, what do I need to consider?

    - by Lasse V. Karlsen
    My question is this: If I'm going to build a DynamicMethod object, corresponding to a ConstructorInfo.Invoke call, what types of IL do I need to implement in order to cope with all (or most) types of arguments, when I can guarantee that the right type and number of arguments is going to be passed in before I make the call? Background I am on my 3rd iteration of my IoC container, and currently doing some profiling to figure out if there are any areas where I can easily shave off large amounts of time being used. One thing I noticed is that when resolving to a concrete type, ultimately I end up with a constructor being called, using ConstructorInfo.Invoke, passing in an array of arguments that I've worked out. What I noticed is that the invoke method has quite a bit of overhead, and I'm wondering if most of this is just different implementations of the same checks I do. For instance, due to the constructor matching code I have, to find a matching constructor for the predefined parameter names, types, and values that I have passed in, there's no way this particular invoke call will not end up with something it should be able to cope with, like the correct number of arguments, in the right order, of the right type, and with appropriate values. When doing a profiling session containing a million calls to my resolve method, and then replacing it with a DynamicMethod implementation that mimics the Invoke call, the profiling timings was like this: ConstructorInfo.Invoke: 1973ms DynamicMethod: 93ms This accounts for around 20% of the total runtime of this profiling application. In other words, by replacing the ConstructorInfo.Invoke call with a DynamicMethod that does the same, I am able to shave off 20% runtime when dealing with basic factory-scoped services (ie. all resolution calls end up with a constructor call). I think this is fairly substantial, and warrants a closer look at how much work it would be to build a stable DynamicMethod generator for constructors in this context. So, the dynamic method would take in an object array, and return the constructed object, and I already know the ConstructorInfo object in question. Therefore, it looks like the dynamic method would be made up of the following IL: l001: ldarg.0 ; the object array containing the arguments l002: ldc.i4.0 ; the index of the first argument l003: ldelem.ref ; get the value of the first argument l004: castclass T ; cast to the right type of argument (only if not "Object") (repeat l001-l004 for all parameters, l004 only for non-Object types, varying l002 constant from 0 and up for each index) l005: newobj ci ; call the constructor l006: ret Is there anything else I need to consider? Note that I'm aware that creating dynamic methods will probably not be available when running the application in "reduced access mode" (sometimes the brain just won't give up those terms), but in that case I can easily detect that and just calling the original constructor as before, with the overhead and all.
