  • MS Access 2003 - Unbound Form uses INSERT statement to save to table; what about subforms?

    - by Justin
    So I have an unbound form that I use to save data to a table on button click. Is there a way I can have subforms for entry that will allow me to save data to the table within that same button click? Basically I want to add more entry options for the user, and while I know other ways to do it, I am particularly curious about doing it this way (if it can be done). So lets say the 'parent form' is frmMain. And there are two child forms "sub1" and "sub2". Just for example sake lets say on frmMain there are two text boxes: txtTitle & txtAuthor. sub1 and sub2 both have a text Box on them that represent something like prices. The idea is Title & author of a book, and then a price at each store (simplified). So I tried this (because I thought it was worth a shot): Dim db as DAO.database Dim sql as String sql = "INSERT INTO (Title, Author, PriceA, PriceB) VALUES (" if not isnull(me.txtTitle) then sql = sql & """" & me.txtTitle & """," Else sql = sql & " NULL," End If if not IsNull(me.txtAuthor) then sql = sql & " """ & me.txtAuthor & """," else sql = sql & " NULL," end if if not IsNull (forms!sub1.txtPrice) then sql = sql & " """ & forms!sub1.txtPrice & """," else sql = sql & " NULL," end if without finishing the code, i think you may see the GOTCHA i am headed for. I tried this and got an "Access cannot find the form "" ". I think I can pretty much see why on this approach too, because when I click the button that calls the new sub form into the parent form, the values that were just entered are not held/saved as sub1 closes and sub2 opens. I should mention that the idea above is not intended to be a one or the other approach, rather both sub forms used everytime. so this is an example. i want to use this method (if possible) to have about 7 different sub form choices in one form, and be able to save to a table via a SQL statement. I realize that there may be better ways, but I am just wondering if I can get there with this approach out of curiousity. Thanks as always!

  • Reading Binary file in C

    - by darkie15
    Hi All, I am having following issue with reading binary file in C. I have read the first 8 bytes of a binary file. Now I need to start reading from the 9th byte. Following is the code: fseek(inputFile, 2*sizeof(int), SEEK_SET); However, when I print the contents of the array where I store the retrieved values, it still shows me the first 8 bytes which is not what I need. Can anyone please help me out with this? Regards, darkie

  • Fragment Shader Eye-Space unscaled depth coordinate

    - by Ben Jones
    I'm trying to use the unscaled (true distance from the front clipping plane) distance to objects in my scene in a GLSL fragment shader. The gl_FragCoord.z value is smaller than I expect. In my vertex shader, I just use ftransform() to set gl_Position. I'm seeing values between 2 and 3 when I expect them to be between 15 and 20. How can I get the real eye-space depth? Thanks!

  • Single Regex for filtering roman numerals from the text files.

    - by Nains
    I am stuck in between of a problem where only one pass of regular expression is allowed( some old hard code). I need the regex for roman numerals. I have tried the standard one i.e. ^(?i)M*(D?C{0,3}|C[DM])(L?X{0,3}|X[LC])(V?I{0,3}|I[VX])$, but the problem is it allows null( '') values also. Is there any way around to check is problem?

  • Date problem in MYSQL Query

    - by davykiash
    Am looking for a query to sum values in a particular time duration say an year or a particular month in an year using MYSQL syntax.Note that my transaction_date column stores daily amount transacted. Am example of a query that returns total sales in an year query would look something like this SELECT SUM(transaction_amount) WHERE transaction_date = (YEAR) Am example of a query that returns total sales in an particular month and year would look something like this SELECT SUM(transaction_amount) WHERE transaction_date = (YEAR)(MONTH) How achievable is this?

  • Calculating length of objects in binary image - algorithm

    - by Jacek
    I need to calculate length of the object in a binary image (maximum distance between the pixels inside the object). As it is a binary image, so we might consider it a 2D array with values 0 (white) and 1 (black). The thing I need is a clever (and preferably simple) algorithm to perform this operation. Keep in mind there are many objects in the image. The image to clarify: Sample input image:

  • Covariance in Java

    - by Bobby
    Why does the following not work in Java? It would work in C#: public static final List<String> Split(String str, char delimiter) { if ((str == null) || "".equals(str)) { return new CopyOnWriteArrayList<String>(); } } I get an error saying this method has to return List. CopyOnWriteArrayList implements the List interface. Why does covariance not apply on return values in Java?

  • How to find minimum of nonlinear, multivariate function using Newton's method (code not linear algeb

    - by Norman Ramsey
    I'm trying to do some parameter estimation and want to choose parameter estimates that minimize the square error in a predicted equation over about 30 variables. If the equation were linear, I would just compute the 30 partial derivatives, set them all to zero, and use a linear-equation solver. But unfortunately the equation is nonlinear and so are its derivatives. If the equation were over a single variable, I would just use Newton's method (also known as Newton-Raphson). The Web is rich in examples and code to implement Newton's method for functions of a single variable. Given that I have about 30 variables, how can I program a numeric solution to this problem using Newton's method? I have the equation in closed form and can compute the first and second derivatives, but I don't know quite how to proceed from there. I have found a large number of treatments on the web, but they quickly get into heavy matrix notation. I've found something moderately helpful on Wikipedia, but I'm having trouble translating it into code. Where I'm worried about breaking down is in the matrix algebra and matrix inversions. I can invert a matrix with a linear-equation solver but I'm worried about getting the right rows and columns, avoiding transposition errors, and so on. To be quite concrete: I want to work with tables mapping variables to their values. I can write a function of such a table that returns the square error given such a table as argument. I can also create functions that return a partial derivative with respect to any given variable. I have a reasonable starting estimate for the values in the table, so I'm not worried about convergence. I'm not sure how to write the loop that uses an estimate (table of value for each variable), the function, and a table of partial-derivative functions to produce a new estimate. That last is what I'd like help with. Any direct help or pointers to good sources will be warmly appreciated. Edit: Since I have the first and second derivatives in closed form, I would like to take advantage of them and avoid more slowly converging methods like simplex searches.

  • Regex negative match query

    - by Matt
    Hey guys, I've got a regex issue, Im trying to ignore just the number '41', I want 4, 1, 14 etc to all match. I've got this [^\b41\b] which is effectively what I want but this also ignores all single iterations of the values 1 and 4. As an example, this matches "41", but I want it to NOT match: \b41\b

  • How to make ARGB transparency using bitwise operators.

    - by Smejda
    I need to make transparency, having 2 pixels: pixel1: {A, R, G, B} - foreground pixel pixel2: {A, R, G, B} - background pixel A,R,G,B are Byte values each color is represented by byte value now I'm calculating transparency as: newR = pixel2_R * alpha / 255 + pixel1_R * (255 - alpha) / 255 newG = pixel2_G * alpha / 255 + pixel1_G * (255 - alpha) / 255 newB = pixel2_B * alpha / 255 + pixel1_B * (255 - alpha) / 255 but it is too slow I need to do it with bitwise operators (AND,OR,XOR, NEGATION, BIT MOVE)

  • NSUserDefaults not present on first run on simulator

    - by Ben Collins
    I've got some settings saved in my Settings.bundle, and I try to use them in application:didFinishLaunchingWithOptions, but on a first run on the simulator accessing objects by key always returns nil (or 0 in the case of ints). Once I go to the settings screen and then exit, they work fine for every run thereafter. What's going on? Isn't the point of using default values in the Settings.bundle to be able to use them without requiring the user to enter them first?

  • jquery data selector

    - by Tauren
    I need to select elements based on values stored in an element's .data() object. At a minimum, I'd like to select top-level data properties using selectors, perhaps like this: $('a').data("category","music"); $('a:data(category=music)'); Or perhaps the selector would be in regular attribute selector format: $('a[category=music]'); Or in attribute format, but with a specifier to indicate it is in .data(): $('a[:category=music]'); I've found James Padolsey's implementation to look simple, yet good. The selector formats above mirror methods shown on that page. There is also this Sizzle patch. For some reason, I recall reading a while back that jQuery 1.4 would include support for selectors on values in the jquery .data() object. However, now that I'm looking for it, I can't find it. Maybe it was just a feature request that I saw. Is there support for this and I'm just not seeing it? Ideally, I'd like to support sub-properties in data() using dot notation. Like this: $('a').data("user",{name: {first:"Tom",last:"Smith"},username: "tomsmith"}); $('a[:user.name.first=Tom]'); I also would like to support multiple data selectors, where only elements with ALL specified data selectors are found. The regular jquery multiple selector does an OR operation. For instance, $('a.big, a.small') selects a tags with either class big or small). I'm looking for an AND, perhaps like this: $('a').data("artist",{id: 3281, name: "Madonna"}); $('a').data("category","music"); $('a[:category=music && :artist.name=Madonna]'); Lastly, it would be great if comparison operators and regex features were available on data selectors. So $(a[:artist.id>5000]) would be possible. I realize I could probably do much of this using filter(), but it would be nice to have a simple selector format. What solutions are available to do this? Is Jame's Padolsey's the best solution at this time? My concern is primarily in regards to performance, but also in the extra features like sub-property dot-notation and multiple data selectors. Are there other implementations that support these things or are better in some way?

  • Validate a long type input

    - by Santiago
    I'm trying to validate that a user only enters a long value as input (long bigger than 0 actually). Compare and Range validator has DataTypeCheck for int values only. I was planning on using this class in a CustomValidator but then I would need to write both, client and server side validation code. Do you know of any other good way of doing this? Thanks!

  • How do you access/configure summaries/snippets in Django Haystack

    - by mlissner
    I'm working on getting django-haystack set up on my site, and am trying to have snippets in my search results roughly like so: Title of result one about Wikis ...this special thing about wiki values is that...I always use a wiki when I walk...snippet value three talks about wikis too...and here's another snippet value about wikis. I know there's a template tag for highlighting, but how do you generate the snippets themselves? I know Solr generates these, but I can't figure out how to get them from Haystack.

Is there an equivalent or another way to accomplish this?

  • How do those bitmasks actually work?

    - by mystify
    For example, this method from NSCalendar takes a bitmask: - (NSDate *)dateByAddingComponents:(NSDateComponents *)comps toDate:(NSDate *)date options:(NSUInteger)opts So options can be like: NSUInteger options = kCFCalendarUnitYear; or like: NSUInteger options = kCFCalendarUnitYear | kCFCalendarUnitMonth | kCFCalendarUnitDay; What I don't get is, how is this actually done? I mean: How can they pull out those values which are merged into options? If I wanted to program something like this, that can take a bitmask, how would that look?

  • Default custom ControlTemplate is not applied when using Style

    - by gehho
    Hi all, I have created a default style for a Button including a custom ControlTemplate like so: <Style TargetType="{x:Type Button}"> <Setter Property="OverridesDefaultStyle" Value="True"/> <Setter Property="Background" Value="White"/> <Setter Property="BorderBrush" Value="Black"/> <!-- ...other property setters... --> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <Grid x:Name="gridMain"> <!-- some content here --> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> This style is added to my shared ResourceDictionary which is loaded by every control. Now, this style/template is applied to all my buttons, as expected, but it is NOT applied to those buttons which locally use a different style. For example, I want to have a certain margin for my "OK", "Apply" and "Cancel" buttons. Therefore, I defined the following style: <Style x:Key="OKApplyCancelStyle" TargetType="{x:Type Button}"> <Setter Property="Margin" Value="4,8"/> <Setter Property="Padding" Value="8,6"/> <Setter Property="MinWidth" Value="100"/> <Setter Property="FontSize" Value="16"/> </Style> ...and applied that style to my buttons using a StaticResource: <Button Content="OK" Style="{StaticResource OKApplyCancelStyle}"/> For me, the expected result would be that the ControlTemplate above would still be applied, using the values for Margin, Padding, MinWidth and FontSize from the "OKApplyCancelStyle". But this is not the case. The default Windows ControlTemplate is used instead, using the values from the style. Is this the typical behavior? Does a local style really override a custom ControlTemplate? If so, how can I achieve my desired behavior? I.e. still use my custom ControlTemplate even when styles are defined locally? Many thanks in advance, gehho.
