    - by I__

  • ms-access: displaying column as "something else"

    - by every_answer_gets_a_point
    i have the following access sql statement: SELECT * FROM (SELECT [Occurrence Number], [Occurrence Date], [1 0 Preanalytical (Before Testing)], [Cup Type], NULL as '2 0 Analytical (Testing Phase)', [2 0 Area], NULL,NULL FROM [Lab Occurrence Form] WHERE NOT ([1 0 Preanalytical (Before Testing)] IS NULL) in this: NULL as '2 0 Analytical (Testing Phase)' when it displays the column it shows the single quote. if i remove the quote completely it gives me an error, if i use double quotes it shows me the double quotes in the resulting table is it possible to not have it show any quotes?

  • How does Access 2007's moveNext/moveFirst/, etc., feature work?

    - by Chris M
    I'm not an Access expert, but am an SQL expert. I inherited an Access front-end referencing a SQL 2005 database that worked OK for about 5000 records, but is failing miserably for 800k records... Behind the scenes in the SQL profiler & activity manager I see some kind of Access query like: SELECT "MS1"."id" FROM "dbo"."customer" "MS1" ORDER BY "MS1"."id" The MS prefix doesn't appear in any Access code I can see. I'm suspicious of the built-in Access navigation code: DoCmd.GoToRecord , , acNext The GoToRecord has AcRecord constant, which includes things like acFirst, acLast, acNext, acPrevious and acGoTo. What does it mean in a database context to move to the "next" record? This particular table uses an identity column as the PK, so is it internally grabbing all the IDs and then moving to the one that is the next highest??? If so, how would it work if a table was comprised of three different fields for the PK? Or am I on the wrong track, and something else in Access is calling that statement? Unfortunately I see a ton of prepared statements in the profiler. THanks!

  • Conditional formatting in Access

    - by every_answer_gets_a_point
    I have a datasheet that looks like this: ID name_ 1 2 3 4 1 name1 x 0 0 0 2 name2 0 x 0 0 3 name3 0 0 x 0 4 name4 0 0 0 x I have rectangles on a report that correspond to this datasheet. When the report opens, I need the rectangles to be colored red according to the data. For example, in the name1 row where there is an x in the 1 column, I need the specific rectangle corresponding to this (name1, 1) to be colored red. Here is the result that I need: x x x x (where x is a rectangle that is red) Perhaps the best place to place this code would be in ON LOAD event of the report, but i am not sure exactly. Can you please suggest to me some code that would turn the specified rectangles red according to the data?

  • how run Access 2007 module in Vb6?

    - by Mahmoud
    I have created a module in access 2007 that will update linked tables, but I wanted to run this module from vb6. I have tried this code from Microsoft, but it didnt work. Sub AccessTest1() Dim A As Object Set A = CreateObject("Access.Application") A.Visible = False A.OpenCurrentDatabase (App.Path & "/DataBase/acc.accdb") A.DoCmd.RunMacro "RefreshLinks" End Sub What I am aiming to do, is to allow my program to update all linked tables to new links, in case the program has been used on other computer In case you want to take a look at the module program, here it is: Sub CreateLinkedJetTable() Dim cat As ADOX.Catalog Dim tbl As ADOX.Table Set cat = New ADOX.Catalog ' Open the catalog. cat.ActiveConnection = CurrentProject.Connection Set tbl = New ADOX.Table ' Create the new table. tbl.Name = "Companies" Set tbl.ParentCatalog = cat ' Set the properties to create the link. tbl.Properties("Jet OLEDB:Link Datasource") = CurrentProject.Path & "/db3.mdb" tbl.Properties("Jet OLEDB:Remote Table Name") = "Companies" tbl.Properties("Jet OLEDB:Create Link") = True ' To link a table with a database password set the Link Provider String ' tbl.Properties("Jet OLEDB:Link Provider String") = "MS Access;PWD=Admin;" ' Append the table to the tables collection. cat.Tables.Append tbl Set cat = Nothing End Sub Sub RefreshLinks() Dim cat As ADOX.Catalog Dim tbl As ADOX.Table Set cat = New ADOX.Catalog ' Open the catalog. cat.ActiveConnection = CurrentProject.Connection Set tbl = New ADOX.Table For Each tbl In cat.Tables ' Verify that the table is a linked table. If tbl.Type = "LINK" Then tbl.Properties("Jet OLEDB:Link Datasource") = CurrentProject.Path & "/db3.mdb" ' To refresh a linked table with a database password set the Link Provider String 'tbl.Properties("Jet OLEDB:Link Provider String") = "MS Access;PWD=Admin;" End If Next End Sub

  • Default Program With Multiple Versions Installed

    - by Optimal Solutions
    I have multiple versions of Excel installed. Excel 2010, 2007 and 2003. I have them installed on one hard drive with Windows 7 Ultimate as the OS. When I double-click on an XLS file, Excel 2007 opens. I would like Excel 2010 to open. I read and followed the instructions to go to the Control Panel at "Control Panel\All Control Panel Items\Default Programs" and set the default programs. I changed the default to the physical EXE for Excel 2010 at the proper folder that it is installed. When I double-click on the XLS files, Excel 2007 still opens. So I tried to change it to Excel 2003 just to see if it changed to that and it still opens Excel 2007. What am I missing? I would really like the file extension to open Excel 2010, but can not seem to do that.

  • getting a combo box that has a row source equal to a query - and the query takes data from a form -

    - by primus285
    I have a combo box with a row source based on an SQL query about like SELECT DISTINCT Database_New.ASEC FROM Database_New WHERE Database_New.Date= DateSerial([cboYear], 1, 1) And Database_New.Date<= DateSerial([cboYear], 12, 31); the trouble is that if I change the value of cboYear, the values in the drop down cboASEC do not update. I have to open the query, save it and close it to get the thing to update while I have the form open. Is there a way to get the cboASEC to update somehow? maybe a little tidbit of code in the cboYear - afterupdate?

  • How do I put data from multiple records into different columns?

    - by Bryan
    My two tables are titled analyzed and analyzedCopy3. I'm trying to put information from analyzedCopy3 into multiple columns in analyzed. Sample data from analyzedCopy3: readings_miu_id OriginalCol ColRSSIz 110001366 Frederick Road -108 110001366 Steel Street 110001366 Fifth Ave. 110001508 Steel Street -104 What I want to do is put the top 3 OriginalCol, ColRSSIz combinations into columns that I have in the table analyzed. In analyzed there is only one record for each unique readings_miu_id. Any ideas? Thanks in advance. Additional Info: By "top 3 OriginalCol, ColRSSIz combinations" I mean the first 3 combinations with the highest value in the ColRSSIz column. For any readings_miu_id there could be anywhere from 1 row of information to 6 rows of information. So at most I'm only wanting the top 3. If there is less than 3 rows for the readings_miu_id then the other columns need to be blank. Query that generates the table "analyzed": strSql4 = " SELECT readings_miu_id, Count(readings_miu_id) as NumberOfReads, First(PercentSuccessz) as PercentSuccess, First(Readingz)as Reading, First(MIUwindowz) as MIUwindow, First(SNz) as SN, First(Noisez) as Noise, First(RSSIz) as RSSI, First(ColRSSIz) as ColRSSI, First(MIURSSIz) as MIURSSI, First(Col1z) as Col1, First(Col1RSSIz) as Col1RSSI, First(Col2z) as Col2, First(Col2RSSIz) as Col2RSSI, First(Col3z) as Col3, First(Col3RSSIz) as Col3RSSI, First(Firmwarez) as Firmware, First(CFGDatez) as CFGDate, First(FreqCorrz) as FreqCorr, First(Activez) as Active, First(MeterTypez) as MeterType, First(OriginColz) as OriginCol, First(ColIDz) as ColID, First(Ownagez) as Ownage, First(SiteIDz) as SiteID, First(PremIDz) as PremID, First(prem_group1z) as prem_group1, First(prem_group2z) as prem_group2, First(ReadIDz) as ReadID, First(prem_addr1z) as prem_addr1 " & _ "INTO analyzed " & _ "FROM analyzedCopy2 " & _ "GROUP BY readings_miu_id, PremIDz; " DoCmd.SetWarnings False DoCmd.RunSQL strSql4 DoCmd.SetWarnings True

  • What's wrong with output parameters?

    - by Chris McCall
    Both in SQL and C#, I've never really liked output parameters. I never passed parameters ByRef in VB6, either. Something about counting on side effects to get something done just bothers me. I know they're a way around not being able to return multiple results from a function, but a rowset in SQL or a complex datatype in C# and VB work just as well, and seem more self-documenting to me. Is there something wrong with my thinking, or are there resources from authoritative sources that back me up? What's your personal take on this and why? What can I say to colleagues that want to design with output parameters that might convince them to use different structures? EDIT: interesting turn- the output parameter I was asking this question about was used in place of a return value. When the return value is "ERROR", the caller is supposed to handle it as an exception. I was doing that but not pleased with the idea. A coworker wasn't informed of the need to handle this condition and as a result, a great deal of money was lost as the procedure failed silently!

  • MS Access Import from Text File problems

    - by Gavin O'Brien
    I'm trying to import a text file into an access database. It's not one I've written myself but the spec for the delimited text file is set up properly and the file imports properly using the wizard. When I try to use the import functions of the app itself, the ImportError table tells "Field Truncation" for one of the fields. Any help would be appreciated.

  • read text file line by line and insert/update values in table

    - by I__
    i am exploring the option of whether DoCmd.TransferText will do what i need, and it seems like it wont. i need to insert data if it does not exist and update it if it does exist i am planning to read a text file line by line like this: Dim intFile As Integer Dim strLine As String intFile = FreeFile() Open myFile For Input As #intFile Line Input #intFile, strLine Close #intFile i guess each individual line will be a record. it will probably be comma separated and some fields will have a " text qualifier because within the field itself i will have commas my question is how would i read a comma delimited text file that has double quotes sometimes as text qualifiers into a table in access?

  • powerpoint macro timer

    - by mustafabattal
    Hi, I have to complete a timer on powerpoint, it countsdown for a specificed amount of time when a shape on particular slide is clicked. I heard macros could be a way to do this, but I have very little knowledge about them. With my research I was able to add a macro and pop out a message box when a shape is clicked*. How can I implement a timer with this? VB syntax is pretty unfamiliar to me. What happens after timer finishes is another question though. *with macro in module: sub hello_world() MsgBox( 'hello world!') end sub

  • Summary statistics in visual basic

    - by ben
    Below I am trying to write a script the goal of which is to calculate some summary statistics for a few different columns of numbers. I have gotten some help on it up to the "Need help below" mark. But beyond that I am flabergasted as to how to calculate the simple stats (sum, mean, standard deviation, coefficient of variation). I know VB has scripts for these stats, which I have included in my code, but I guess I need to do some extra declaring or something. Advice much appreciated. Thanks.

  • Access startup form locked GUI

    - by Brad
    I just had an interesting experience with a startup form in MS Access 2010. I designed a login form and when I thought I was done I set my startup form to be the login form I'd just created. I then closed Access and reopened it but my login form did not appear. Instead the whole GUI was locked. I cannot click on anything. My form was working during my tests before I set it as a startup form and reloaded Access. How can I either remove my form as a startup object or get the use of my GUI back?
